Michael's wife here: For reference I'm 5'4" and weigh around 175 lbs. I usually wear a 12 so I got the 13. Looked like a size 1 but material was super stretchy.
Pros: stretchy material, nice blue color (didn't look or feel cheap to me), love the way my butt looks in these
Cons: one size too small. unfortunately the sizing goes up to 13 only.
I'll be returning it and continue my search for the next perfect jeans.
