its a really nice pair of shorts, fit so comfortable, im 5’5 148 lbs 26 waist . i usually fit size 5 in jeans if its non stretch, & a 3 for stretchy material. i usually do a medium depending on the material and type of item, but 8/10 i fit in a small comfortably. id honestly size down to a XS when i repurchase these just because i want a little bit more snug cheekier look to the shorts & the small to me fits like a medium, so if your like my measurements & slim small waist, hip dips etc size down 2 .
