I love this skirt. I am 5'7" and 260 lbs. Most of my weight is in the middle and rear. I got 5x. Normally, I don't need that big of a size but the material is stretchy and it runs small. So I would highly recommend getting a size or two bigger than you normally would.
The other review I posted had the incorrect picture. Although I will say, the kenzie & rosemary have the same fit and are pretty much the same except for the hem.
