Bought 2 sizes for my boys. For my 4 year old who is just starting to fit 4T I bought him a size 5-6x hoping it would be a bit big but he would grow with it. It suits him perfectly. I bought another one for my 6 year old son who is a bit chubby. It's a size 7s. I bought him a size 7-8. In fact, when it's zipped up, it's a little tight. I think they are worth the price BUT these jackets are a bit small for my average sized kids. Luckily it's not that much as the price for it is very good. The jacket itself is very good and should last this winter.
