I'm 5 ft. 6 in. tall/130lbs. and I bought size medium. I have to pull the drawstring pretty tight (I should mention that my butt is so flat, it's almost concave, LOL) and probably could have stood to order size small but am always fearful that whatever I've ordered won't fit. Since they have a drawstring and a bit of elastic, though, it's no problem.

These fit so nice. 5'5 145pds. 38\\\\\\\" waist, I'm more athletic build, I don't have a thin waist, no backside. These fit great, they have room would probably fit most figures. The pockets aren't real shallow. I didn't know if I'd like the elastic at the bottom but it's loose, the pants drape over. The waist goes up just high enough. Might be needing another pair.

I'm 5'3\\\\\\\" so the legs are long but the bottom of the leg has elastic which is not tight around ankles and pants do not drag on ground which give the look more of harem pants... and my husband really likes the look. Strongly recommend!
