We ordered 5T for our skinny daughter. What was popular was the XX-Small, which was still too big for her. Although it comes with a belt, I still had to add a 1 inch button to keep it from falling off. The good news is that there is still one more season to go. The material makes a robust impression and lasts a long time.
