"I bought size 2T - True to size. I have a little girl and I've decided to bedazzle it and add a tule tutu to the sock monkey. :-) I couldn't find anything better for this price online anywhere! If it's cold outside I will just put a long sleeve shirt on underneath. It's perfect no matter the season. On the invite I told the other guests/kids to "wear red or white so the pictures are fun and bright!" I also purchased several other sock monkey items and this party will be "CLASSIC" AND adorable."
