Just so you have an idea of my size I am 510, around 165lbs, 36 G bra and I am in pretty good shape. The dress fits me pretty good. The dress isn't clingy the way polyester is but because of the cut of the dress any extra weight will be emphasized. The material is soft, medium thickness and sits about 4 above my knee cap. I love it though. I have a second one (lavender) and it fits great too. I will buy more when they go on sale again.
