There are no noticeable stains, but please note that this is a used item and I may have missed something. Please purchase only if you understand that this is a used item. There are pockets on both sides. I think the waist is high-waisted. (Because it completely covers my stomach) It's size S, but the waist is elastic, so even I, who usually wear M, could wear it with room to spare. When shipping, it will be folded compactly, so please be aware of any creases. k1
