I had been looking at this bikini for a long time, but now that I finally got it, I'm a little disappointed. Based on other reviews I was expecting incredible support, but I feel that my boobs sit really low with this top and it's not flattering. Also, the top of my breasts are pressed flat, which makes them look saggier than they really are. If I was in the UK, I'd probably exchange it for one cup size up to see if that helps the problem, but I'm not sure if it would.
On a positive note: I feel secure in it despite the bandeau style. Because it sits so low, I do feel more comfortable with the halterneck strap because I feel that pulls it up about a centimeter, but I think it is equally reliable without the strap.
