Labels, labels, labels. It seems at times we just can't avoid them, much less get them right. Still, there's one label that a lot of those of us who are MtF get wrong needlessly, something we share with a majority of natal women.
I'm speaking of course about the label to be found on our bras. There is no need for a label debate about that one, it's an issue that can be solved with five minutes use of a tape measure, yet
so many people get it wrong and wear the wrong size.
As MtF crossdressers or transsexuals we have an extra disadvantage over natal women, we're not taught about these things as teenagers and those who are in the closet may find it difficult to walk into a lingerie store and ask for a fitting without embarrassment. In addition there are still too many suppliers selling breastforms without adequate sizing information, so those of us who need a little artificial enhancement may find ourselves not even knowing what cup size we've bought.
So here follows a quick guide to measuring yourself and selecting the right bra size. It won't guarantee an eye-catching result, but it should at least lead you to a more comfortable fit and help you avoid the escaping boob look, or worse still, the escaping breastform look.
Take two measurements in inches, one round your chest just under the bust and one round your chest over the bust itself, or over your breastforms if you wear them. Round the under-bust measurement up to the nearest even inch and that will be your band size. Take the difference between the two measurements in inches, if it is below one inch you are an A cup, if an inch you are a B cup, if two inches a C and so on. The table below gives a full cross-reference of this measurement versus cup size differences for UK and US sizing.
Over the bust/chest measurement difference and cup size
Band | inch | 0 | <1 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 |
Cupsize | U.S. | A | AA | B | C | D | DD | DDD/E/F | DDDD/F/G | G/H/J | I/J/K | J | K | L | M | N | - | - | - |
Cupsize | UK/Austr. | A | AA | B | C | D | DD | E | F | FF | G | GG | H | HH | J | JJ | K | KK | L |

So for example if your under-bust measurement is 39.5 inches and your over-bust measurement is 44 inches then the difference is about 4 inches and you need a 40DD bra.
Which means you should be all set to go and order the perfect undergarment. Assuming of course that you remembered to use a fabric tape rather than a steel one, you would not
believe how cold a steel tape can be!
