Trinity wants to be Sleeping Beauty

My challenge is to create a costume for Trinity (2 1/2) that looks something like this. When her mama brought home a pretty Snow White costume for Madison, suddenly the hand-me-down Ariel costume didn't appeal to her. She cried for a princess dress, to be Sleeping Beauty. I will do my best to make her feel special. She's a little young to understand the lessons that could be taught at a time like this. We'll save those for another day. Today I want to make my little granddaughter happy.
