A little large/long but good quality. I think my son is pretty average sized for an 8 year old. My fault for getting it last minute so we didn’t have time to get it fitted. The quality was better than expected especially for the price. He told me he was super comfortable in it so that was the biggest win! Shirt not included and he took his jacket off for the picture.

Very nice material. Sizes are accurate. I love it. I bought size 6 for my 7 year old son ( he's a little on the smaller size) and Size 12 for my 10 year old ( he's tallish and skinny) because I want them to last a few years.
