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.
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,

A broke down last year and just got measured at VS. Came out to a 42C and got a wonderful pushup bra.
Has anyone noticed it’s hard to get size 16 or U.S, equal “B” cup bras.
I’ve found a nice padded bra in “B” cup that FITS GREAT, try going back to
Target to get the same again, not easy.
I have only read a page of these comments but the thing that every single article about measuring for a bra leaves out, whether it is here or Elle or Cosmo or a web site for women or a site for bra sales, (whew!), is this: You need someone to do it with you. It is impossible to hold the tape loose enough so the girls are not getting squeezed yet tight enough to stay in place. It is a 2 girl job. Even if you have someone measuring you, the tape should be held in place by you at 2 points to keep it in the right place. Currently, mine are each a full handful when lying on my back. Depending on how I hold the tape that means anywhere from 36 to 39 across the nipples. Downside, the girljuice seems to make the tummy grow too. Two steps forward, one step back. Darn!
I had a bra fitting at M&S a couple of years ago and, as I struggled to fill an A cup, the assistant suggested I wear T-shirt bras as they would give a smoother look.
I have now been taking pureira mirifica in the last few months and my breasts have not only increased in size but are a nice shape as well. I can now wear a 38B and fill the cups and my breasts are noticeable under a thin top even if i don’t wear a bra. I hope to end up as a “small” 38C.
I still wear my 38A bras to the gym (along with a gym skirt) as my breasts need some cover when I’m running on the treadmill but they’re stretching a bit now so I’ll need to get some 38B bras soon. What with using them for the gym and everyday wear I’ll need to buy around a dozen bras…this could get expensive…but well worth it !

“Pete”…You Are “One Lucky Girl”…I’m So Happy For You !
But it’s a great feeling isn’t it!

For years we were all using a method of measurement that was absolutely wrong–no wonder we are wearing the wrong bras. The old method said that measure around your back and your ribcage at the point where your bra sits (bottom edge of the band of a bra) and then ADD FIVE INCHES!!! Then, take another measurement across the fullest part of your bust. The difference is your cup size. Using this method always failed–at least for me. If I took that under the bra band measurement and didn’t add anything to it–then took the across the fullest part measurement (my nipples in a bra), figured the difference–it worked 90% of the time. I wear a 42 C bra (thanks estradiol–without implants) which fits perfectly. My cups are full without spillage, the band is comfortable and it looks fantastic–so much so that my GG girlfriend (34 B) gets jealous.
