I bought these for cold LA nights. Until then, I'm a boxy, bulky body type. Basically my shoulders and legs are huge and I have a stomach. I bought the XL, they fit me, I didn't want them to be too skinny when I need to be comfortable in a "fancy" place. If I wanted them to be puffy, I think an XXL size would be better. They are by no means tight but are a "more appropriate" size if you have big feet like mine!
