Personally I love fashion nova jeans, but they run bigger than said size. Im 5’2, a medium size girl with short legs and a long torso. I typically wear a size 7/8 in standard jeans but I have to get a 5. They’re very long and stretchy. If you’re petite size down.
Broad statement, not all of their jeans have the same stretchiness. You have to look at “materials” under the product. Some jeans have 0 stretch, others have 3%, 5%, etc
