I bought one for my 3 yr old (size 4 - because he is a rather solid fellow) and it fits well with some room to grow. I ordered another fleece (Rhymes with ROLO) from somewhere else for my 6 yr old. I didn't think it was near the quality and fit of this fleece. I am ordering one now for my 6 yr old in a different color as the similar color has been sold out in his size. Understandable... as the fleece is that sharp.Hope this helps.Cheers.
