FOX's Scream Queens has been on the air for three weeks now, and it's already one of our favorite shows. With such sassy female leads, the style for the debut season had to be on point. Chanel Oberlin's closet makes Cher Horowitz's look so last year, and costume designer Lou Eyrich explains all, with Emma Roberts by her side. As you can see in the behind-the-scenes video, everything in the trailer is absolutely fabulous. If looks could kill, we'd be happy to die in vintage Alice + Olivia, Dior, and Chanel, too.
