I have a sweet spot skirt. I bought it at a Tri or a race a couple of years ago. Actually, I have two. One is the snap one and kind of a canvas material and the other one is a tech material and kind of 'fluttery' in styling. Both are great, but I prefer the fluttery one.

They do fit a wide range of sizes.

Here is a photo of me in the canvas one after a race (from a few years ago):
