These run small,as in tight! I usually wear a size 4 in American Eagle jeans, but I had to return these jeans twice ( a size 5 and a size 7) before I got a size that fit me, which ended up being a size 9. They do have a lot of stretch, though, and the material is thin and soft, which is the way I like it. I bought these for a 70's party, and I received several compliments on them, including from my much younger niece (she's 25), who stated that she wanted a pair. I took away one star because there are no options regarding the length, and these are too long for me
