Gently worn one evening. Surprisingly well made for costume store outfit. Lined jacket. Pants with adjustable waist. Gloves and neck tie. Even come with Zero dog!!!! We put a leach on zero and walked him around with costume Says size small 4-6. My son is 7 and wears a 6-7 and this fit perfect. He is also tall and these pants were perfect!! In my opinion it would be a 7-8.
