Is a size 32A bra too small?

Answer 1

People who truly fit into 32As are extremely rare, and are called "unicorns" in the online bra fitting community because of it.

Someone who would wear a 32A would have a ribcage that equals 32 inches, no adding numbers, and a bust that equals 33 inches, since all an A cup means is that there is a 1 inch difference between the ribcage and the bust.

There is no such thing as a "too small" or "too large" bra size. It's just a bra size, one that is supposed to hug your body and provide support.
