I'm a size 6-8 for my 7 year old girl (about 4ft 2in and 50lbs). She always complains about the top of her tights so I figured a stirrup would do. But they were too small for her. Legs fit well (see photo with black dress) but crotch didn't come close to true to size. They fit my 4 year old perfectly (approx 3ft 4in 33lbs) - see photos with pink dress. Full Disclosure - I received this item at a discount in exchange for my honest review.
