This dress is super stretchy and comfy so don't worry about sizing up. The material is quite thin and you can definitely see my thong and booty skin even though the dress is a dark color. I think this dress is flattering for many body types. For me I don't feel comfortable wearing it just yet. It shows off EVERYTHING. From the front on me it looks smoking hot. From the side it highlights all of my most insecure, problem areas. Definitely keeping it and doing more core exercises though.
