I typically wear a small in bralettes or sports bras - these fit around my torso very well but the surface area in the front is just not enough for my 34B bust. For lack of a more gentle way to explain, I was either spilling out over the top or squeezing out under the bottom. I was unable to return them so they will work in a pinch for a lounge bra but I don't think I'll be wearing them in public!
