I usually range from US sizes 38G-38H and bought this as UK 38FF (US 38H). This fits better than my bras. It's amazing. Looks good, too. I got this and Panache's bikini top combined with one of their bikini bottoms so I could switch easily between modest and skimpy. It shows off a little without squeezing you to death or making you fall out of it, which makes it better than anything I've bought in a retail store. My only complaints are that the piece dividing the breasts really digs in after a while and the little strap in the back lends to some back fat squish-out if you don't shift it around a bit.
