An FF cup bikini top only works if it is constructed like a bra: underwired cups with real depth, firm side support and straps that adjust. Triangle and stretch tops have nothing to lift with at this size.
Mix, match and fit
Every top here is sold in your bra size, so you can buy the top and the bottom separately and have both actually fit — which is the usual problem with a matched set at FF. Buy your bra size rather than sizing to a neighbouring cup, which is what leaves the bust sitting low.
