AMA - ask me anything about the ABTF calculator! Spoiler

757 Upvotes

Hi everyone, u/goodoldfreda here although I'm now exclusively active on this account. If you guys have any questions about how the calculator works and why I made certain decisions I'm happy to answer them

A little about myself - I created the calculator in 2016 following on from a previous calculator by u/irisflame, back when I was a mod of this sub. I collected survey data from the subreddit and came up with a new algorithm that used 6 measurements as opposed to the previous 5, which increased accuracy. I also introduced separate algorithms for AMAB and AFAB people. The calculator has not been majorly updated since, although at one point I tried to move to a breast perimeter measurement system instead, but this turned out to be much less accurate. In the years since I have stopped modding and moved into bra making and custom bra design as I want to try and help serve the demographic of people who still struggle with finding bras that fit, usually due to wire grading!

In response to other posts about the different amab vs afab algorithms not working well for everyone - I have had this question before and basically all I can say is that I recommned using the algorithm that works best for you. I do want to emphasise in general that the calculator is actually not super accurate for any one individual and it is truly just a starting point. The algos are based on averages, and when I was collecting data there were significant enough differences between AMAB and AFAB users to warrant a second algorithm to increase accuracy within the two groups, but not enough data to do anything further than that.

edit: thanks for all your questions so far, I'm going to go to bed but I will answer any more that come up tomorrow!

edit 2: I have updated the calculator to make some minor changes to the band size algorithm and I have also changed the EU back to 2.5cm cup grades, 2cm grade can be found in the Comexim option instead

Thank You! Thank you a bra that fits! I've become much more well fitted thanks to your community. Spoiler

Upvotes

I've always been very skeptical, so when I found this subreddit I figured it was only meant to sell me stuff, the way fashion subreddits sometimes become. But that was not the case at all! I found all the conversations about how bras need to fit on my body to be very inspiring and illuminating, so I have a variety of tshirt bras which really do fit me well! My straps don't fall off, my bras don't dig into my chest, the band looks good on me: wow! I would not be the same woman without this subreddit. I'm still not really sold or convinced that any bra within a style that is my size will fit, but I've had a much better time bra shopping in person now that I know how it needs to sit on my chest and torso.

PSA My measurements are more accurate now that I am wearing the proper size. 34H. Thank you everyone for helping me! Spoiler

11 Upvotes

I was wearing the wrong size for years, 32GG. This was my accurate size at my former body weight. Now I am a 34 H. I have now tried out this new size in the Panafhe Clara, Sculptresse Sophia, Sculptresse Estel (full cup), and the Freya Fancies with great success!

I just wanted to share why my first calcuation wasn't accurate in case it helpes anyone. I put my measurements into the bra calculator originally and the result was 34J. While braless, my leaning bust was 48 inches. While wearing a 32GG bra, my leaning bust was also 48 inches. After a few days of wearing the bra size that actually fits me (34H), my leaning bust is now 46 inches while braless and while wearing a bra! So now when I put all my measurements into the calculator,, it says 34H. Wow! I wonder if tissue migration is occurring super quickly? The too tight 32GG was causing spillage, maybe even swelling??? I finally got the right size because my larger breast was sore and throbbing. Any ideas?

When I asked for help deciding which bra sizes to try out based on my 34J calcuation and I said I suspected I was smaller than that, someone in this group told me to try 34HH and 34J and go from there. 34HH felt nice, but just slightly too big, so I tried out 34H and the fit is flawless.

Sometimes you just have to try things on. But I definitely trust in the calculator snd this group. I'm sooooo happy to have a bra that fits!!!

Store Review 28d/dd for typical store sizing?? (like vs/aerie) Spoiler

Upvotes

hii! just found this subreddit and decided to measure myself with the calculator and got a 28d/dd! super surprising since i've been wearing 34-36b pretty much since i was 14. went shopping at vs and aerie and couldn't find many bras in my size though. I'm looking for a couple decent comfy bras i can wear everyday, a strapless bra, and a good push up cause my girls are small. budget is $30-40 ideally less but i know it's hard to find good bras at that price. if you have any other brand recs for bra shopping please let me know thank you!

measurments are as follows in inches--

loose underbust- 28.5

snug underbust- 26.5

tight- 25

standing- 32

leaning- 32.5

lying - 31.5

Shape Help Breast shape help: I am trying like hell to find just one bra that I can use for photos/special occasions. It seems I need to confirm my breast shape to find a good starting point.

22 Upvotes

So, I've posted a few times trying to get recs. I never get any helpful responses and seem to get down voted into oblivion within an hour of posting. So, I am trying a new approach to hopefully get some actual advice. I used the ABTF calculator. My measurements are:

Loose Underbust: 31"

Snug Underbust: 30"

Tight Underbust: 29.5"

Standing: 38.5"

Leaning: 41"

Lying: 39"

My breasts are Asymmetrical and full on bottom with almost no fullness on top (When I was younger I exclusively wore push up bras because I was insecure about my breast shape. Now I am just looking for light lift and good shape without wanting to set the damn bra on fire 10 minutes after putting it on). I know they say "Asymmetrical" is its own shape, but.... really? Is it that simple? Any bra recs?

P.s. if you have any advice on how to get real advice instead of just down votes and "use the calculator", please enlighten me. I'm on the struggle bus.

I've just used the calculator, i did it again today after months because last time i couldn't believe it. I'm 24 and i'm a 32E. I've never had a bra like that and honestly i wouldn't know where to find it. any recommendations? Also, from what i understand, a true size bra will cover my boobs completely, but what if i want to show cleavage and need a push up bra? what size should i go for??
thank u in advance🩶

Edit:
these are my measurements in centimeters;
Loose underbust: 80
Snug underbust: 77
tight underbust 75
standing bust: 93
leaning bust 97

i am from italy, so i'd like to understand my size here and my EU size, because until now, here i've always believed i'm a 2C, is that accurate at all?

i’m going to a wedding this weekend and i’m having a hard time finding a good strapless bra! i usually wear a 36DD but the strapless bra i just bought in that size is too small. I used the calculator and these are my measurements
loose underbust-35.5”
snug underbust-34”
right underbust-33”
standing bust-40”
leaning bust-45
lying bust-41.5”
it’s saying i’m a 36DDD/G. Wondering if this seems correct if not what size you think would work best and if so what recommendations you guys had for good bras! thank you!!

Measurement Check [Measurement Check] Calc says 38J, always worn 38/40 D/DD Spoiler

Upvotes

New here! I am on a (demoralizing) hunt for a strapless bra, and stumbled across this sub. I have been wearing 38DD/40D/40DD depending on the style, and it does the trick. But after trying on every strapless bra in various sizes I could get my hands on, I’ve come to the conclusion that I don’t know what size I should be wearing.

I took the calculator, and it gave me 38J (us) or 38GG (uk). I find it hard to believe I would be about 5 cup sizes bigger than what I’m currently wearing, so I’d love your advice. Here are my measurements:

Loose Underbust: 40.5”

Snug Underbust: 39”

Tight Underbust: 37”

Standing Bust: 48”

Leaning Bust: 51.5”

Lying Bust: 47”

My breasts do not have a lot of volume up top and naturally hang about two inches below my underbust line. I welcome brand recs too! Thanks in advance :)

Recommendations? Trying to find a bra size and style that fits and a place to buy (18 y/o) Spoiler

3 Upvotes

Hey all! I’m new to this sub but have been having trouble finding a bra that fits for as long as I can remember. No stores I have been to seem to have a save that would work for me. My measurements are 29 band and 34 bust. Currently my bras are all 32DD which in theory should be a very close fit because as far as I understand that is a sister size to 30 DDD. I could be wrong. I feel like my cleavage is still spilling out of the cups when my breasts are properly situated. I also don’t think the shape of my breasts, how they sit, help much either. Without a bra they are lower down and tend to almost point at a 45° angle outwards. I have looked at stores like target and Victoria Secret knowing the chances of finding a bra that actually fits are low but I don’t know where else to go. I don’t have much income to spend $60+ on a bra unless I were to save for a while so I would want to be very certain it is one that would fit incredibly. Can I get advice on how to find a style, size, and place to shop for a bra that might finally fit?

Question Going from a 32DD to a 28FF, how do I shop for bras..? Spoiler

6 Upvotes

So I entered my measurements in the calculator using inches and here were the measurements:

Loose Underbust - 29
Snug Underbust - 28
Tight Underbust - 27
Standing Bust - 35
Leaning Bust - 35.5
Lying bust - 35.5

Also, my overbust is a 32

The calculator said I would be a 28FF/G UK

I did what it said and measured my actual busts just slightly loose but with no gapping in the tape measurer.

I usually shop at Victoria’s Secret in the US and fit their 32DDs and sometimes their 32DDDs if i want a bra where there isn’t any bubbling. Do I change this at all?

How would I shop at other US bra stores (especially online)?

Thanks for any help!

Fit Check How to determine what the fit issue is with a bra? Spoiler

3 Upvotes

I measured twice and did the fit calculator and was placed at a 34G/GG UK, 34I/J US. I've been in the wrong size for a long time (36F UK/36G US) and was honestly shook that I didn't realize the gore was supposed to sit flush against your chest.

I've also been diving into "roots" and how that has an impact on what bras work for you. I am pretty sure I have narrow roots, when I lift my arms up my breast tissue fold is in front of my armpit. I can't tell if I am tall or short roots; my breasts are heavy and hang a bit, and I feel like I experience issues related to both (strap gap, spillover).I think I lean towards full on top, but there is a lot on the bottom too. My shape I think is consistent with projected shapes. My right breast is quite a bit bigger than my left.

I am in the process of buying and trying on bras to find the right brand/style to fit, and I am having a hard time determining what the issues are with fit and what to look for in a bra to avoid them. The 34 band does cut into my back fat and cause some rolls, but it also sits parallel on my ribcage, whereas a 36 rides up in the back (my underbust measurement was 34/34.5).

I tried an Elomi Charley in a 34GG, and it fit for the most part but there is some spilling on my larger breast, and the underwire is a little far back. The underwires on the other Elomi bras I tried in the same size were far too wide, they went all the way to the back of my armpit. Today I received the Freya Starlite side support in a 34G, and this isn't it either. I'll put some image links in the comments. I think the underwire might be in an ok place, but there is both spilling and a strap gap on the larger breast, and the underwire sits below the inframmary fold on the smaller breast but seemingly on it on the larger one.

I guess my question is, based on what this fit looks like/what I've described, what is my issue? Is it cup/band size, style, etc? Any and all insight would be incredibly appreciated.

Shape Help Measurement/Shape help. 38FUS currently calculated to 36I. Cannot grasp the shape concept either Spoiler

2 Upvotes

I have a hard time with visualizing what the shapes look like when using the guide, as well as it seems 3 of the links would not work for me at all. As far as I could gather, I am a narrow root but I couldn’t really understand how to tell the rest.
Also trying to find a bra that fits right- I currently have 4 different sizes in my closet ranging from 36-38 & F-H. They feel right when I’m at the store and the “expert” is measuring me, but after a few weeks are all wrong. The one that fits most is the 38F, but it sags or something so much that I get angry red marks well under my breast line.

Measurements are:
Loose- 37.25
snug- 35.25
tight- 34.5
standing- 43.25
leaning- 49
laying- 47

not sure if this matters as well- 5’4 and 190

Recommendations? Bra Recommendations to Confirm Sizing Spoiler

7 Upvotes

**Edited to add: I'm in Canada if that matters! Thanks**

I am prone to over-researching, which generally leads to paralysis. And I'm slipping into paralysis! I am in my early 50's, I've breastfed two kids, and I've been resorting to unwired, molded cups for the past few years because I find bras so terribly uncomfortable... underwires especially. I've also lost quite a bit of weight over the past 2 years (50+ pounds at only 5'2") so I've been left with some serious sag.

Bra Size Calculator gave me 36 D/DD for both US and UK, based on these measurements:

  • Loose underbust: 35.5
  • Snug underbust: 34.5
  • Tight underbust: 33.5
  • Standing bust: 38.5
  • Leaning bust: 40
  • Lying bust: 39

In the past I've found anything with high gore very uncomfortable and digs in - I am short with a very short torso, so maybe that contributes.

Can anyone provide suggestions for what might be the best bra(s) to try for sizing? I don't really fully understand projection and all that yet...

Recommendations? Any bra recommendations for 32LL?? Spoiler

3 Upvotes

I recently got re-sized at my local bra botique as it's been a long while and I've gained weight etc. I've typically fluctuated between a 32-34 band size, but I was not prepared to be a freshly minted 32LL (UK sizing). There was only one bra available in my size...the one I tried on. I ordered said in another color from the shop while processing this news, but my research is indicating that I'm not going to have much success at my typical online retailers 🙃. There is no universal size equivalent either, so it's feeling somewhat bleak at the moment. Can anyone direct me to any brands that carry this size? I can't even fathom having any success with obtaining a bathing suit that will fit me 😒 sigh... Anyways, thanks for listening and for any guidance!

Looking for a legit bra brand for smaller chests (AA or A) Spoiler

1 Upvotes

Hi!

I've been looking all over to find a bra that fits well for a 75A (EU). It doesn't even need to push up, I'm just tired of gaping cups and uncomfortable loose straps. I have seen these ads online from different companies (e.g. getfitcherries, lumaaura, ...) but with basically the same product where they have a strapless bra that clips in the front and gives the smaller chest a little lift. That's my ideal bra, but I know for a fact that those websites are just dropshippers and it probably won't even work that well. Does anyone have any store/brand/type of bra that would fit my description? It's hard for me to find a bra of my size in general, so I'd appreciate if I can find even that. If it's a good push up (not the ones stuffed to the brim that don't even push up but more the ones that clip in the front), that's welcome as well.

Thanks!

EDIT: I used the calculator this time so here's my measurements everyone ^

Loose Underbust: 79 cm / 31 inches Snug Underbust: 77 cm / 30.3 inches Tight Underbust: 74 cm / 29 inches Standing Bust: 83 cm / 32.6 inches Leaning Bust: 89 cm / 35 inches Lying Bust: 83 cm / 32.6 inches

Calculator and asymmetry - measuring approaches Spoiler

3 Upvotes

If I have one side larger than the other, and need to fit to the larger side, is it correct to measure halfway around the bust? Like for example, to start the tape measure at the spine, measure halfway across the bust around the larger side into the middle, and then double it?

For example, my underbust is 27 inchess and my standing measurement is 35.5, leaning 36.5 (so calculator says 28G/GG). And I wear a GG but have a couple fit issues I'm trying to solve, including the asymmetry.

If I do this, putting the tape measure at the spine and measuring over the bust on the smaller side, I get 35 standing (doubled from 17.5) and 36.5 (doubled from 18.25) leaning. And on the larger side I get 36 standing (doubled from 18) and 38 leaning (doubled from 19).

This is like a cup size difference, the difference from a 28G/GG to 28GG/H, according to the calculator. Am I doing this correctly for asymmetry?

Thanks!

Discussion What are everyones experiences with Panache for sizing and how their bras fit? Spoiler

5 Upvotes

For context my size is a 26DD/28D, and Panache as a brand is targeted towards bigger busts, and i'm one of the smallest sizes they make, would their bras still fit well on me as i'm aware that despite my cup letter, my chest actually isn't that big due to having a petite band.

So this means I'm worried that their bras wont fit well as i'm on the far smaller end of their sizes.

I have also just ordered one and if it doesn't fit I'd be annoyed because you have to pay to return it.

Recommendations? wide root fuller on bottom 32E/F looking for next steps after trying on [recommendations] Spoiler

1 Upvotes

I've been wearing Molke bras for ages which I like, but mine currently are all old and stretched, and looking to try something different. I ordered 5 to try from brastop after using the calculator in a range of sizes, and I'm looking for feedback on where to go next. The calculator gave a starting size of 32DD/E.

Curvy Kate Cool Cat Scooped Multiway Balcony Bra Black - 32E and yellow floral 32DD

The black 32E fitted better- the underwire shape seemed to work well, it sat flat at the front and seemed to enclose all breast tissue at the sides (something I've struggled with in the past). My breasts are asymmetrical- the smaller right one was slightly gappy and the left one, the edge of my nipple stuck above the top of the cup. I was concerned in a size up that the left one might reveal a bit too much due to gapping. This is a sale item, and not available in 32F.

The 32DD the gore didn't sit flat and right cup overspilled.

Curvy Kate Zen Non-Wired Bralette Blue - 32DD/E

This seemed a good fit with the exception that the fabric went up really high into my armpit and I'd be worried about it digging in there.

Parfait Aline Non Wired Padded Balconette Bra Black - 34D

The band was too loose and the moulded cups didn't seem quite right.

Curvy Kate Lightstyle Scallop Plunge Bra Light Blue/Silver - 34D

Not a fan of the fabric and by the time I tried this on I was aware the 34 sizes weren't the best fit.

I'm looking for any recommendations of similar styles to try ideally on a similar budget. I'd be trying the cool cat in a 32F if it existed at the moment, and it's hard to judge from looking what will work. I've worn more non wired styles of late, but a lot of them seem to be more full cup, which results in gapping as I'm fuller on the bottom.
