So for the Zombie Walk and Halloween, a group of friends and I decided to make some Black Lantern costumes from DC Comics' Blackest Night story arc. I chose Ice solely because I liked the costume, but then grew to love the character. Probably one of my favourite costumes to date.
The entire thing was made by me, from drafting the patterns to actually constructing it. The contacts I'm wearing are these ones here: http://www.youknowit.com/online-shop/white-screen-contact-lenses-pair.cfm
They're screens so you can still see through them (though they are a bit murky.) They're surprisingly comfortable, despite this.
