Best friend and couples Halloween costumes are great, but who better to accompany you on the year’s spookiest night than your own flesh and blood? OK, you don’t necessarily need a sister to dress in these fantastic pop culture looks, but you might want to grab a buddy to pull off these sister costumes.
If you want to go with a literal sister look-alike costume for Halloween this year, you’ll find great inspiration from classics like “Sister, Sister” – which stars real-life twins Tia and Tamera Mowry – and “The Parent Trap,” where Lindsay Lohan pulls double-duty as Hallie and Annie. Or perhaps you love sister witches: in that case, you should look to “Sabrina the Teenage Witch” or the “Hocus Pocus” movies to find the best sister costume ideas. Or maybe you and your bestie just want matching outfits so you go as multiple versions of Beyoncé from her “Lemonade” era.
Whichever sister Halloween costumes you’re in search of this year, you’re sure to find the perfect look up here. We’ve compiled some of the most creative, iconic sister characters from popular movies and TV shows for this list. Want to go old-school with “The Brady Bunch”? How about medieval for some “Game of Thrones” looks? Whatever your jam, we’ve got your ideal Halloween costumes for sisters up ahead.

Sister Halloween Costumes: Nancy and Barb From "Stranger Things"
- What to wear: For Nancy, get a long, brown wig, and pin it back on both sides of your head. Then, pair it with a cutesy striped sweater or button-down (buttoned all the way up, naturally), and a high-waisted skirt or jeans. If you go for a skirt, make sure you wear it with white tights and flats. Keep in mind Nancy’s cool accessories, which include her homework, notebooks, and a bat. For Barb, mimic her short red hairstyle, then get a plaid shirt with as many ruffles as possible, high-waisted light-wash (mom) jeans, a thin watch, and some Sally Jessy Raphael glasses. Feel free to tote around a fake notebook or binder.
- How to act: By the end of season one, Nancy proves herself to be not only book smart, but street smart as well. Be the girl with the plan on Oct. 31. Barb is a little bit aloof and uncomfortable in social situations, and acts a bit like Nancy’s mom throughout the show. Stay away from any pools, and refuse any and all offers of beer, especially if someone asks you to shotgun it.
