We had a hat contest for Easter last week and my niece wore her unicorn head and won $100 from our Aunt. First kid to win the hat decorating contest.


My daughter absolutely loves her unicorn costume. My daughter is 4 and wanted to put this together herself, but needed my assistance. However, I do believe this project was rated for older children. It looks great. The other kids and parents in the area want to know where we got it.

My son LOVES his Unicorn costume. We had such a wonderful time creating it together.
