Take it from someone who has dressed up as Madonna on three different Halloweens: She is a fount of easy and amazing costume ideas. Her look is so versatile! You can repurpose last year's sexed-up Sandy from Grease outfit into Madonna's iconic "Papa Don't Preach" vampy black bustier and capris. Have a bloodied zombie getup from three years ago? Paint a tooth gap between your front two chompers... Madonna the Dead! Only own lingerie? Madge approves of this fashion choice—you could say you're the Material Girl in dozens of iterations. Hell, she even dressed up as a Boy Scout at the GLAAD Awards in 2013—and those unis are a dime a dozen at thrift stores.

With 30-plus years of noteworthy outfits to choose from, Ms. Ciccone could inspire Halloween costumes for the rest of your life. The following are just a few ways of channeling your inner Queen of Pop. Just remember this handy motto: When in doubt, let your butt hang out.

Like a Madonna

This one's immediately recognizable as "Madonna." Combine tutu, bustier, gloves, belts, and baubles—all easily found at your local thrift shop. Rat up the hair, apply the beauty mark, and tubularize the makeup. And if there's another Madonna at the Halloween party? Just claim to be the nearly '80s-identical Cyndi Lauper. TWOFER!
