I know that this bra is manufactured with UK sizes and there is a conversion chart showing the correct US equivalent, but when I received the bra, the US and UK size have the same letter on the tag (which they shouldn't) and the cup size is too small (it is the US size on the tag, which is a cup size too small for me). I don't know if the bra is defective or just mislabeled. I believe that if I were sent the proper size it may fit. It has a comfortable band, the cups are comfortable (though I do think there is way too much padding, especially for a cup size like mine), but the sizing is off.
