Hopefully, you've seen the awesomeness that is The Labyrinth. My brother decided to be David Bowie's character, Jarreth. And it was full of awesome.
We bought his wig on ebay. Everything else was either made or thrifted. He wore women's boots for the costume, but I bet you Bowie did too. ; ) I did his make up with everyday cosmetic and assembled him a cool scepter thingy. Enjoy!
