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!

Thanks, Lucille! now I know that I’m starting the program with a 36AA cup
Imagine my surprise when I first noticed my breasts were really growing.
I now wear a bra with a B Cup. I really enjoy wearing my lingerie and make sure it’s trimmed with lace. Just being the woman I was meant to be is thrilling and shopping for just the right sizes is wonderful!
Hi Lucille,
I have just purchased a few front closer bras. I now have a good range of bras. From underwire & wire-free bras/and crop tops. I was measured a 22b, (in lingerie store), I went up a size to 24b with breast forms. The 24b bra fits comfortably. I also have a variety of women’s panties/briefs/shapewear. I have not worn male underwear (briefs) for 2 years. In summer at work I sweat & would get a rash due to the leg band in the men’s briefs.
Lucille,
Once again you are so helpful. I am going shopping for new bras. My goal to be a “passable” lady requires a good feminine presentation and breast as so important.
Have fun dressing

Imagine my surprise when I first noticed my breasts were really growing.
I now wear a bra with a C Cup. I really enjoy wearing my lingerie and make sure it’s trimmed with lace. Just being the woman I was meant to be is thrilling and shopping for just the right sizes is wonderful!
I read a story about men who wear bra’s. It dealt with the subject of Gynecomastia. It this article it talked about finding a specialty bra shop and having a professional fitting there. I did a search for bra shops in my area. I wrote asking if they would do a fitting on men. They replied yes they would. I made an appointment and went for a fitting with my breast forms. I was measured at a 34DD. I do have to say the company was very discreet. Even taking me into a private room due to natural women being in the store. It was so women did not feel uncomfortable with myself being a customer and getting a fitting.
Well whatever works for you. I guess everyone is different. I personally developed 36 B-34 C on hormones.
what kind of hormones
Bra bands stretch fairly forgivingly, and, as Lucille points out, band extenders can also be used. For me (and my manly chest), it turns out that a bra with a smaller band size and a larger cup size than my measurements imply, actually does a better shaping job. It’s just numbers; I’m happy with whatever works.
Hi Joan, different styles of bras have different sizes.
