Fly away in this DIY [1] costume.

What you need to do: For the girls, any long, flowing white dress will do. You can also wear a billowy white top and trousers or a nightgown. Curl your hair, and tie it into a casual ponytail. For the guys, wear green trousers and an oversized green t-shirt with the bottom trimmed into triangles. Use green felt and a red feather to create the hat.
