I'm planning a starfire cosplay, and ran across this wonderful cosplayer! I love her Idea for how she did her skin, and figured I would repost her great idea! (hope she doesn't mind!!!!!)
"The skin - Mehron Liquid Make-up for Face, Body, and Hair in orange - http://www.mehron.com/Liquid_Makeup_p/111.htm
- I added it to a body lotion and then slathered it all over my skin like bright orange sunscreen!"
