Ring halter bikini top in best buds

I ordered a medium in this top since I am a 34C. This top stays put and easily ties and unties. The fabric is strong and smooth. The only issue that might arise is if you want a little more coverage, than go up a size. I ordered the matching bottom in medium which covers my butt. I really like this style of bikini and wish there were more color options so I can purchase more.
