I ordered this in a 2X and the fit was fine overall. But if you are larger on top, you will probably be really exposed. The material is silky and pretty flimsy. It is L-O-N-G too - I am 5'7" and it drags on the floor. I will probably use it to lounge around home or for sleeping. Not bad for what you get, but you might not want to wear it out, depending on how comfortable you are with the exposure factor. The adjustable straps is a good idea, though.
