It’s impossible not to feel totally girly in a beautiful bra…
But did you know there’s a good chance you are wearing the WRONG size bra?
Don’t feel bad… 80% of bra wearers are too! This includes crossdressers and transgender women – as well as cisgender (genetic) women.
Wearing the correct bra size is critical. Bras that don’t fit right are uncomfortable and look bad under your clothes.
In this blog post, I’ll show you how to find your correct MTF bra size so you can choose the perfect bra for your female transformation.
How to Determine Your Correct Bra Size – Without Breast Forms
Determining your correct bra size begins with a choice: Will you be wearing breast forms with the bra?
In this section, I’ll explain how to find the correct bra size for your ACTUAL breasts (without breast forms). In the section below, I’ll show you how to find the correct bra size if you wear breast forms.
There are several ways to measure your bra size. The method below is simplest way to measure your bra size. This method is used by Victoria’s Secret and most modern bra manufacturers:
Step 1: Measure your band size
Place a tape measure under your arms and measure your chest circumference just above the breasts. The tape measure should be about the level where your bra straps meet the bra.
This measurement is your BAND SIZE. (Note: If the measurement is an odd number, round down to the nearest even number.)
Step 2: Measure your bust size
Stand up tall and measure across the fullest part of your bust. The tape measure should be parallel to the floor and shouldn’t be too tight or too loose.
This is your BUST SIZE. (Note: If the measurement is between inches, round up to the nearest inch.)
Step 3: Calculate your cup size
Subtract your band size (from Step 1) from your bust size (from Step 2) and check the chart below to determine your cup size:
If The Difference Is: | Your Cup Size Is: |
0″-1/2″ (1.3 cm) | AA |
1/2″- 1″ (2.6 cm) | A |
2″ (5.1 cm) | B |
3″ (7.6 cm) | C |
4″ (10.2 cm) | D |
5″ (12.7 cm) | DD or E |
6″ (15.2 cm) | DDD or F |
7″ (17.8 cm) | G |
8″ (20.3 cm) | H |
9” (22.9 cm) | I |
10″ (25.4 cm) | J |
For example, if your band size is 40” and your bust size is 44”, the difference is 4”. That would make you a D cup.
Your bra size is a combination of your band size and your cup size. (Bra size = band size + cup size) In this case, your bra size would be a 40D.
IMPORTANT: This size should be considered a starting point, as sizing varies from bra to bra. If possible, try on the actual bra before you buy.
How to Determine Your Correct Bra Size – With Breast Forms
If you wear breast forms, the process for finding your bra size is a bit different. Here’s how to do it:
Step 1: Measure your band size
(Note: These instructions are the same as above, but I’ll repeat them here.)
Place a tape measure under your arms and measure your chest circumference just above the breasts. The tape measure should be about the level where your bra straps meet the bra.
This measurement is your BAND SIZE. (Note: If the measurement is an odd number, round down to the nearest even number.)
Step 2: Determine your ideal cup size
The next step is to determine the cup size you want to achieve. This should be a size that’s proportionate to your body: Not too big and not too small.
Generally speaking, the larger your body frame is, the larger your cup size should be.
Here are some guidelines:
- Choose an B or C cup if you have a small frame.
- Choose a C or D cup if you have a medium frame.
- Choose a D cup or larger if you have a large frame.
Once you know your correct band size and desired cup size, you can purchase the proper bra and breast forms.
Easy right? 🙂
Finding A Bra That Fits
Knowing your correct bra size is one thing. Actually FINDING that bra is another.
Unfortunately, it’s not always easy to find bras outside the standard size range.
Here are some sites that carry a large range of bra sizes:
- Barenecessities.com – Bare Necessities offers a huge selection of bras, including plus size bras with smaller cup sizes. (Perfect for girls who don’t wear breast forms.)
- HerRoom.com – Her Room is another large lingerie site that stocks hard to find sizes. They offer band sizes up to 58, so there’s a bra for almost everybody.
- BiggerBras.com – BiggerBras.com specializes in plus size bras and carries a large range of cup sizes.
Another option is to purchase a bra extender. A bra extender is an elasticized piece of fabric that hooks onto the back of your bra. It can add 1-3 inches to the bra band, so it’s a great solution for bras that are too tight.
So there you are, girlfriend! Everything you need to know about finding your correct bra size.
As always, I’d love to hear your thoughts! Please leave me your comments below. And if you have any beautiful bra pics, don’t forget to include them!
Love,
Lucille

Hello,
While researching how to best help the trans clients at my lingerie shop, I came across this article.
Specialty stores with actual fit training always measure the band size by measuring under the bust where the bra actually sits, not up under your arms. If you measure 35″ under your bust, you’d wear a 36. No adding four or five inches as other places suggest, or measuring band size anywhere but where the band goes.
Got fitted many years ago and it was a great experience. The lady was very helpful and passed on a ton of knowledge that has come in handy for a long time.
This was very informative and helpful. I have been wearing the wrong size for Oh so many years and now wearing the rights size feels so natural. Thank You for all the wonderful tips and advice. Being of larger frame My bra size is 46E
Found your article very helpful and informational!!! Thank you for that. I am a 38 B cup. I absolutely love my body since I have grown my breasts. It just feels right to have something real in my bra and to show off that girlish figure!! Hoping to get to a C cup someday, but no rush..
Good for you. When I was young I wish the internet existed. I would have transitioned for sure at age 25. I sure wish I had breasts. The best thing I ever did for myself was buying good silicone inserts. When I wear them I really feel like they are real.
this article helps me out since I’m currently going through the transtion
I found this helpful and wearing a bra does bring out the inner woman
Hi my name is michelle
Im crossdress i would need help about my bras
My botton is 36″ and my bras is 38, what is it my real bras size?
36 B, though you may need to try on some sizes slightly larger/smaller in cups and band to get the best fit.
Also, every bra company sizes things slightly differently, and breasts come in more then one shape.
Unfortunately, bra shopping is often trial and error to get a good fit.
I’m a new crossdresser and I need a help to know my bra size
My band size is 37″ and bust size is 39. What will be my actual bra size?
