Im kinda a snob about my clothes, so I was hesitant on ordering these shorts. Im 54, 140# and ordered a Large, while I normally wear Medium. They are super stretchy and plenty long without being too long. They fit great in the waist and legs. Dont necessarily lift the butt but I don't need that anyway. Super happy with these! Ordered white and black. White is a bit see-through so you need to wear white/nude panties with them.
