This is a really cute jacket, but older, and the size tags are worn, as shown in the next to last photo. Sleeve length is 10”, chest measures 27”, and waist is 26” measured around and not laid flat. I am thinking that it's a size 6 for little boys, but check the measurements before buying. In very good pre-owned condition. Normal wear and tear noted, but no flaws or damage. Please review pictures and feel free to ask any questions or for more pictures prior to purchasing.YYY
