I'm normally size 3/5 in my jeans (5'6" 140lbs). I would've gotten size 3 but they were sold out. So I bought a size 5 which fits ok. They're comfortable and stretchy. The cuffed part is not sown so you can roll it or unroll it as you please. They're a little loose in the waist area but it's probably cause I should've gotten a smaller size. Lol they're cute either way!
