I am an adult woman & ordered a size medium. The item was sooo small it probably couldn't fit on one of my legs. Maybe it could fit a child under 10. Since it is a "women's bustier" I assumed it was designed for an adult woman. Even if I got an XXXL it still would not have been big enuf. Worse than that, the seller wouldn't refund my shipping cost- which is half the cost of the item itself. So a COMPLETE WASTE OF $$$.
