Have you heard of this cute cartoon, Masha and the Bear? It's a super cute show.
My sister recently made a costume for a little girl who was Masha for Halloween. She had some leftover fabric, so she made another play dress in size 2T and can make one in different little girl sizes. The listing is here on Etsy for the ready made size 2T or for a Custom Made Masha and the Bear dress size 2T-6.
