Levi'sWomen's Premium 501 Skinny Jeans

Having trouble figuring out sizing for non-stretch. If waist fits, behind is flattened. Will the waistband shrink and the butt stretch to fit?

Can you return if they don’t fit ?

I’m 5’2” with a curvy/athletic build.. What inseam should I get?

do these have the traditional 501 button fly or zipper and button?
