I have bought stuff on wish. I'm 5'6", about 125lbs and the largest size they sell fits me okay, not a great fit but good enough. It takes about three weeks to ship. Returns are a no-go, but if the stuff doesn't show up or if it shows up broken they refund your money. They even have a thing where they'll email you and ask if the item has arrived, and if it hasn't they offer to refund your money. I did this once and the item showed up a week later. Their policy is that if this happens, you keep the item free of charge. Beware, though, the quality is not great. But for leggings or doll house furniture I think it's fine. I got some cute leggings dirt cheap. All in all, not a scam. IMO of course.
