sizing chart

This dress is a super cute style & shipped pretty quickly; but I had to exchange it for a smaller size. I went by my 53" bust, so got the 5x, based on the size/measurement chart. Thought that seemed big, even for a Junior's dress; and sure enough, i just stepped into it without unzipping it, and it was HUGE, falling off of me. The top runs about 3" bigger than the sizing/measurement chart indicates. Just wanted people to have a better idea of what size to order.
