It’s so bad that my fiancée has some bras that say she’s a B cup and others that says she’s a D cup. In order to go bra shopping, you have to actually try them on to find out if they fit.

If I had to try on underwear to see if they fit, I might not bother with underwear at all!

    I don’t think you know how the bra size system works. The number is the size measured underneath the breasts. The letter is the cup size determined as a the difference between the measurements across and underneath the breasts.

    Therefore no way is 32D equivalent to 34B. Or at least it shouldn’t be equivalent, but manufacturers don’t respect the standard, so the equivalence is not impossible in some cases. It’s really super inconsistent.

    Also breasts can have different shapes and can be placed closer or further appart, which makes finding a fitting bra very hard for some people.

      32 + 4 = 36

      34 + 2 = 36

      Am I missing something? Barring some extremely stupid math error, I don’t see how I’m incorrect

        You’re close! Both a 34B and a 32D would have the same measurement around their bust, but the bust size alone can’t be used to determine bra size. The rule is to increase band size by 1 increment (which is 2”) and reduce cup size by 1 increment (the letter) to maintain the same volume.

        The volume of a 32D is the same as a 34C.

        Omg, just realised this must be the way manufacturers think about bras, that would explain a lot 😆
