I bought these to go with the matching top, and I love the look as a set! But the shorts were a tiny bit snug in the waist & didn’t go with the boxy oversized look of the top. So I sized up one in the shorts & they're roomy now the way I think they should fit. They are flowy & the pockets and drawstring waist are awesome. For reference, I’m 5’5” and 120 lbs, and I returned the small for the medium. I do not ever wear a medium, so I would say they run small. (But that depends on the look you want, of course)
