It seems like in our culture, the 'DD' bra size is seen as 'huge' or 'desirable'. This statement in itself doesn't make sense, because a DD measurement is simply saying that the chest measurement is five inches larger than the rib cage measurement. It doesn't actually have anything to do with breast size. For a bra measurement, the same cup size will be assigned a different letter, depending on the band size. For example:
28DD = 30D = 32C = 34B = 36A
The cups in all of these bras will look the same; the band will just be a different length. This often means that women with small rib cages will have the most difficulty finding bras that fit because the average store doesn't carry an abundance of 28 and 30 band sizes, irrespective of cup size -- but that's another issue.
We have had customers go through the fit guide and find that instead of being a B cup, they turn out to be a DD cup, and they contact us because they're sure a mistake has been made -- their breasts aren't DDs! But when they try on the new size, they realize the difference it makes in fit and support.
So if you're on our website for the first time and think you might be here by accident because there's no way you're a D cup or larger, give us a chance. Ignore the myth and go through the fit guide -- you might be surprised at the result!
