Here's what you need:
* white pants, or capris, must be used with suspenders which must be spraypainted white
- green hairspray
- orange facepaint
- white overalls or pants*
- crazy socks
- white shoes
Thanks to Kayla for this great idea!
I was an Oompa Loompa last year for Halloween, and the socks aren't crazy - they are white and brown striped (horizontally), and match the turtleneck and cuffs of the brown shirt, Kayla seemed to have forgotten. Also, these guys wear brown shoes with that curl up, not white.
Thanks for this additional information from Diane
