It's time for tricks and treats, and, of course, fabulous Halloween costumes — cue our special edition Halloween DIY series! MOD is having a major fashion moment right now, thanks to Marc Jacobs's Spring 2013 collection, to which he cited Edie Sedgwick at the root of his inspiration. In this DIY, our FabSugar Reporter Allison McNamara is showing you how to make your very own '60s-inspired costume. All you need is a black dress, some white paint, and you're ready to go.
