"Baby girl Cocomelon tutu outfit. Great for a first birthday or any day. I use premium soft pink and green tulle, double faced satin ribbon. Watermelon seeds are glitter black felt. Sizing: This is a good size for babies 6 months through 12 months and is 6 inches in length. The waist is 17\" non stretched elastic.
