I wear 32w 32l  with levis jeans (unless particularly skinny) and this item fit perfectly.
It's more of a 'slim' fit than a regular, but very pleasantly so, slightly tighter than 511 jeans on legs, but it looks fashionably slim, while still keeping my huge thighs comfortable (my thighs are about 1,5x the size of someone of my built, years of intense soccer).

It sits low, slightly below the waistline (but not ass-crack-revealingly so) and doesn't ride up between legs.

Would never imagine I'd buy my best-fitting jean-short online, but got lucky with this.
