Are costumes not your thing? These looks are for you. Reach into your closet for a cable-knit turtleneck sweater, black skirt, tights, and loafers, and bam: You’re Sally from When Harry Met Sally. It’s as easy as that. Need a Harry? Convince a preppy friend to go as him. All they need are jeans, white sneakers, and a fisherman sweater to pull it off. Stick together, and when people question who you guys are dressed as, prepare for a lot of, “Omg, I see it now.”
