The ribbed material version like solid black, red, yellow, etc fit true to size and are very comfortable and flattering. I suggest getting black to totally hide that the bikini has pads, which is not listed in product details. I got an xs in the ribbed version and I'm a small 32B and there was room ...if I was a little bigger. Moving on to the printed hibiscus bikini top — this is a spandex material like a speedo and not ribbed like the solid color ones. I got an xs in this top but it was very tight under the armpits. It created good cleavage but it was a little too snug. It also has pads which the product details section fails to mention. I would have kept it but the distracting print isn't even so one breast looked normal and the other distorted by the print. I don't think this would be a problem for larger sizes. In general I would size up for the hibiscus spandex print and keep your normal size for the ribbed solid colors ones, noting the ribbed ones can have room due to the stretch
