This Halloween, we're throwing it back to the 1990s. We've handpicked some pop culture '90s icons who would make, like, totally easy costumes. Think: Spice Girls; Wednesday from "The Addams Family," and Romy and Michele from "Romy and Michele's High School Reunion." Since '90s fashion trends are basically always in style - chunky sneakers, choker necklaces, and bucket hats - it's refreshingly easy to DIY a perfect '90s Halloween costume from your closet. Have bike shorts and a crewneck sweatshirt? You are now Princess Diana.
