Waist: Approximately 40cm Length: Approximately 20cm Thigh circumference: Approximately 28cm Made of 100% cotton corduroy. I think it should be fine for a standard build. My grandchild wore this size normally until they were 3 years old. You can remove the elastic from the thighs to make it a culotte. You can replace the elastic yourself. Convenient to wear under dresses and skirts, and cute worn over tights or spats. ◎ This is a handmade item by an amateur, so please understand and purchase accordingly.
