I bought this hat for my son (even though its labeled as girl's). I needed something that he wouldn't rip off his head and I was willing to try anything and everything. About 75% of the time he leaves it alone ( I think due to the softness) so it's a keeper in my book! and it looks so darling on! it is not fully lined as i thought it might be, but i think this is for the best, as it might get too hot if it was. the lining is so soft and the soft blue color is so cute! i thought it would be great to pass down to another baby sister or brother. I ordered the 2T for my one year old whose head is in the 50% percentile and it fits pretty snug, so i'd definitely order a larger size than you think you may need!
