This is our pro cut back. It is the most narrow cut we offer. It is much smaller than the sweetheart cut and the full cut. It is pretty much a thong at the bottom. All suits are made for you after the order is placed. You can choose color, suit size and the type of back you would like. This is just a type of back we offer. You are NOT buying an actual bottom, just the style. And it does NOT come with rhinestones.
