I can see why you’re struggling to find jeans that fit a 13″ rise as some denim brands go as high as 12″. It really depends on what your size is as the rise of jeans gets higher as the size gets bigger. So if you were a plus size you may find this easier than if you are petite. Check out these jeans for a 13″ rise or near enough – Levis High Loose Super high rise: 13.125″. Levis 720 high rise super skinny plus size High rise: 12.5″. Everlane way high jean Rise: 12 1/8”. I hope this helps, let me know how you get on.
