This set is so cute. The top has never been worn but the bottoms have somewhere to them. I bought this for my daughter and she never wore the top but she wore the bottoms all the time. The waist runs small for a medium. They are 13 inches unstretched. In the waist. And they stretched to about 17 inches across the front. The inseam is 30 inches. There is some pilling on the pants from being washed but the top is like new. The under arm under arm is 22 inches across the front and the length is 24 inches. It’s all super soft and stretchy.
