Colorful AB crystals, not clear ones! the Jeans have some stretch to them so I would say get your actual size unless you have extra extra curves. I have a mom pouch so I choose to get a size 18p and probably could fit either a 16p for a more snug fit but the 18p is a more comfortable fit on me. They give me extra room in the hips and bum without feeling constrained. The details are beautiful but I don't know how the will hold up to cleaning. ( Dry Clean ) and keep some extra crystals and fabric glue on hand for emergency repairs. I'm 5'3, 16p/18p. 48-40-49 198lb.
