River island bikini set

Purchased from ASOS, only wore the top once and the bottoms are brand new with tags and protective polythene sticker. Bikini top has detachable straps and is a UK8 which is a US12. I wear a C cup and it fits but would say best fits a B or someone in between. Top features side cut out slits. Bottoms are high waisted which also have two slits on each side which falls around the hip bone. Bottoms are a size 8 also.
