These bras are beautiful!  They are made from a satiny, smooth material that is so comfortable against the skin.  The cup liners help to prevent against any unwelcome "showing" and they are appropriately supportive for someone with small breasts (34A for reference).  I intend these for running and other training activities, including those that involve impact and the support seems adequate (although I can imagine more well-endowed women finding these entirely lacking in the support department).  All in all, if you are smaller chested (or perhaps larger chested and just looking for light support), I would recommend these!  Plus you can't beat the price!
