I really like this outfit and i liked getting the outfit and hat for about $9 on sale on Amazon. The hat is a little small in comparison to the outfit. My Baby is in the 25th percentile for height and weight at 3 months and the 6 month hat fits her snugly and the outfit is a little big but not outrageously big. She will be able to grow into the outfit a bit but not the hat. When i received the hat and outfit there were some strings hanging from some of the bows but i just clipped then off. I would say just  order 1 size bigger than your babies age.
