When Fall arrived in September, we knew Halloween [1] was one step closer to being here. Then it was officially October, but we were still waiting to get into the Halloween spirit. Now, the event we've all been waiting for is here: the Scream Queens [2] Halloween episode. "Halloween Blues" is airing on Oct. 18, and it features a blue Chanel (it's a medical condition, but she embraces it with a Smurf costume), Dr. Cassidy as Ryan Lochte (so topical!), and a casually fierce-looking Zayday. While you're busy getting your Scream Queens costumes [3] together, take a look at what the gang is wearing for Chanel-O-Ween!
