This Chinese bra does not appear to have been made for the US market, as most of the label is in Chinese. The band size is given (40/90, US/EU) but no cup size is specified. The cups are small, probably A or AA. Soft cotton material, the underwire cups are lightly padded and have a diagonal seam and snaps to allow them to be opened for nursing. Stretch straps adjust in front. Three sets of three hooks in back.
