Since I get asked the same questions about this costume a lot, I figured I'd write up an FAQ for interested parties:
Q: Where did you get your wig?
A: My Finn made it for me. It was made out of two long wigs-- one 48 inch, one 60 inch. They were purchased on Ebay. I don't know the seller, sorry!
Q: How did you do the makeup?
A: It is Ben Nye Character Series cream makeup in Ghoul Grey (CB-8). It was applied using latex makeup sponges and sealed with Ben Nye Neutral Set Colorless Powder and hairspray. I do not recommend using hairspray unless you have someone helping you apply the makeup.
You can buy it here: http://www.frendsbeautysupplyonline.com/bennyecharacterbasecb-8ghoulgrey.aspx for only $3.40!
Q: How much makeup did you use?
A: Evicted! : Medium Coverage (face, neck, chest, shoulders, arms, hands)
Henchmen: Medium Coverage (face, neck, chest, shoulders, arms, hands)
It Came From the Nightosphere**: Minimum Coverage (face, neck, hands)
Heat Signature: Medium
