This is a 4 way knitted bra that gives superb stretch to conform to body shape. It is ruched in the middle to give more definition and uplift. Also has a wide ribbed band at the bottom so no digging in to the skin, and wide shoulder straps. It has a round neck at front and back. This bra goes by dress size and not bra size, however if you wear a small chest size but big cup size it is better to order one size bigger.
