So I ended up buying a size medium in the Coral and a small in the black and I actually love both sizes! The Coral is a super duper neon hot pink (see pics) which is exactly what I was hoping for. The medium definitely has more coverage, but the size small is still nice to have for the days I don't really care about showing more skin. Here are a couple pics of the size medium (pink) and small (black) side by side. Just ordered another one in the neon yellow because I love this suit so much :)

For reference- I am 56 120 lbs, bust 32D/34C
