Sister Halloween Costumes That You and Your Built-in Besties Can Agree On

Yes, DIY Halloween costumes for couples are fun—but have you ever thought about hitting the neighborhood on October 31 with your best pal and sister? After all, she's your other soulmate, and she's always been down for a silly adventure! Whether you’re searching for Halloween costumes for kids or DIY Halloween costumes for women, these DIY sister Halloween costumes make pulling off matching looks an absolute breeze. Besides, who'd want to go it alone?

Here, we've pulled together our favorite two-in-one looks so you can spend less time researching and more time dressing up (and hoarding the best Halloween candy, of course). Just imagine running amok in Hocus Pocus-inspired Sanderson sisters costumes, Elsa and Anna Frozen costumes, or as The Wizard of Oz’s Glinda and Wicked Witch.

Not sure where to even begin? We suggest writing down your shared interests, including favorite foods, films, and even fairy tales, and then selecting a costume from our picks based on the things that speak to items on your list. Maybe you're fans of country music, for instance—in which case, a Reba and Dolly Parton ensemble might be just the thing for you!

Alternatively, if you're picking out a costume for your own little ones, we'd encourage you to think about mimicking a famous and easily recognizable "duo" for a funny and creative kiddie costume. Think: a set of dice, corresponding lemonade and ice cream stand ensembles, or even Scooby Doo costumes. You and your go-to gal can’t go wrong with any of these handmade Halloween costumes for sisters, which you can easily whip up at the last minute—just in time for trick-or-treating!
