10 Sister Costume Ideas You'd Only Want To Be With Your Other Half


If you and your sister are best friends, you've most likely been coordinating Halloween costumes ever since you were kids. You channeled your inner Disney princesses, got decked out in Lisa Frank outfits, and went as your favorite Power Rangers. You naturally have tons of quality #TBT pictures from each year you went trick-or-treating in your neighborhood. I know I can muster up a lot of Instagram likes on a prime throwback picture of my sister and I on Halloween. Even though you're not kids anymore, that does not mean you can't still coordinate costumes to totally slay whatever Halloween party you're going to together. There are plenty of sister Halloween costume ideas you both can rock.

For real though, you know there's no one else that you would rather do a Halloween costume with other than your sister. She's your other half, partner in crime, and best friend in the whole world. Plus, you've both been killing it with the costume game for years. Why would you ever stray away? You can go with a fun topical costume, something creepy, or something totally nostalgic from your childhood. Either way, you know you are going to look great with your BFF sister. You have some time to plan out the perfect Halloween costume, but if you and your sister are blanking on what to be, here are 10 sister costume ideas to consider.

1. Anna And Elsa From Frozen

If you're both hardcore Disney fans, why not be the ultimate Disney sisters, Anna and Elsa? You'll totally melt the hearts of everyone you see. And who knows, maybe after all the Halloween parties, you and your sister can go home and attempt to build a snowman together with all of your Halloween candy.

2. The Adventures of Pete & Pete Characters

You can't go wrong with a good Nickelodeon throwback costume. It'll hit you right with all of the nostalgic feels. That's why these Little Pete and Strongest Man in the World costumes are awesome.

3. The Proud Family Squad

If you watched The Proud Family, you know how awesome these costumes are. You and your sister can totally rock Penny Proud and her friends as a Halloween costume. Bonus points if one of you dresses up like Sugar Mama.

4. Cute And Simple Fruit Costumes

This idea is super simple. You pick out a fruit, buy a T-shirt in the right color, and put a stem on your head. This is perfect for the sisters who are lazy AF and want to throw something together last-minute.

5. Lilo & Stitch

These DIY Lilo & Stitch costumes are super cute. It's a great tutu take on some of your favorite TV characters. This costume idea is also so perfect for you and your sister, because Lilo & Stitch is all about "'ohana," which means "family."

6. A Devil And An Angel

If you know one of you was always the good kid and one was the rebellious sister, you can be an angel and a devil. This is a simple Halloween costume, but it's such a classic. Heck, you could even switch up the roles just for Halloween night to confuse the heck out of everyone.

7. Buzz And Woody

Pixar characters are always a hit. You and your sister can be Buzz and Woody from Toy Story. It's also a great costume because you know when it comes to your sister, "you've got a friend in me."

8. The Grady Twins From The Shining

If you really want to creep everyone out this Halloween, you and your sister can be the Grady twins. This is a classic for any sister duo. It's also perfect if you were looking for more of a scary costume.

9. Your Favorite Riverdale Characters

If you and your sister are like me, you cannot wait for the next season of Riverdale. So, why not be your favorite characters from the show? You could be Betty and Veronica, or Josie and the Pussycats.

10. The Sanderson Sisters

You and your sis can be the ultimate Halloween sisters, aka, the Sanderson sisters from Hocus Pocus. Everyone will love your costume because for any true 90s baby, you're the symbol of Halloween. It's the ultimate sister costume, and you and your other half can cause "amuck amuck amuck" all night long.
