H&M have really nice skinny jeans in my opinion and they are relatively cheap. Also go by stores like Ross and Good Will they might have some really good skinny jeans.

See if there's a local secondhand store near you such as Plato's Closet. Sometimes you can find brand new clothes there with the original tags for cheap! If they fit everywhere else but the waist, then have them taken in by either a tailor, friend/parent or doing it yourself. You'll still save money compared to buying them brand new or at the main store.
