Ordered for my 4 year old, shes not a fan of Toy Story but was needed for a parade she was going to come out on. I ordered the small which is 4-6x, it did fit her, not tight or loose, for reference shes 45 lbs and 42 inches tall. Overall its a good jumpsuit, its not stretchy and the material looks a little thick, so Im assuming it will get pretty hot during the summer. The hat is unusable, its cardboard material and it won't stay out on her head. Other than that it the jumpsuit serves its purpose.
