Is a size 32A bra too small?

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.
