It is about true to size, maybe a bit small. My 4.5 year old models size 5/6 years. he is small for his age. (He is about 43 inches tall and weighs 35-36 pounds). It's still a bit big for him, which is great since he can grow into it! This is an adorable coat. My two small criticisms are that there are 4 very good front pockets but no side pockets to put cold hands in. Also, the charming and soft plaid fleece lining the inside of this coat doesn't completely tuck into your hands. But overall it's still a great coat!
