I purchased the Levi jacket for my nephew. He looks so cute.  He wears a size 5. I ordered a.size 6. I wanted him to be able to wear it for next season too. The length of the sleeves and body of jacket are great. Room to grow. When buttoned over a shirt, it fits great. I'm not sure about another season. My nephew isn't husky or chubby; average build. The jacket is also warm. And my nephew loves it. The final stamp of approval was the immediate instagram posting of my nephew in the jacket by my hard to please sister. Definitely recommend the jacket.
