I was pleasantly surprised to see that it fit as well as it does, there is probably a 4" or so flap in the back that sits under the laces or you can fold it to one side to see some skin. There's plenty of room for adjustment too, so ordering one size small may be wanted if you like too cinch it down tight. The quality is a lot better than expected and the fabric, harness, and zipper are pretty decent too. The thong that comes with it is kind of a joke, but was fun for us to laugh at. I bought this for my wife while she was out of town for work and took a guess on the size after reading reviews, we've bought quite a few other clothes  on here and it's nice to have help figuring sizing out. She's 5'2", DD cup, and about 140lbs give or take and i ordered the XL. It shipped really fast too and was here the next day.
