I'm small chested (A-cup) and, lets be honest, I never need the sort of support that is required for larger chested women. Ever. This bra is comfortable and unbinding. I never find myself trying to stretch it out or itch underneath it. The fabric is very thin, so it breathes well and dries fast, and because it doesn't have cups built into the it, it doesn't pucker. I wear a 34A and am a comfortable size medium is this bra.
