I’m a size 35 waist (already kind of an unfortunate measurement bc pants are usually even numbers idk I wear a belt when necessary- what’s it to ya, toots?) so I got a large and they are pretty much form fitting. I have an athletic build so my thighs and dumper carry a heavy burden on the daily. I’d size up but then the waist would be too wide. They are nice and all, but thick thighs are supposed save lives. I can’t save lives in these shorts. I look good as hell tho.
