The Best Halloween Costumes for Sisters

Updated on September 23, 2015

Turn Halloween From "Ah!" to "Aw!"

When I trying to decide what costumes to choose for my two girls on their first Halloween together, I found there was a ton of adorable ideas out there. It was hard to pick just one, so I've listed them all here!

Many of these ideas, especially those with animal costumes, would also work for girls with younger brothers. Because of this, I also suggest dressing up any animal costumes with pink hair bows or jewelry of some kind, since it does get a little old to have people look at your daughter and say "Oh, isn't he cute!" all Halloween long. Trust me, I know.

These costume ideas work well for sisters that are twins, close in age, or really big and really little sister pairs. There are quite a few that work for three or more sisters as well. Try these ideas yourself with your sister, best friend, or cousin!

Halloween Costumes for Big Girls With Little Twin Sisters

(From Brave) Merida and her younger bear siblings
Works well with more than one bear sibling!
Monkey and banana
The twins can both dress as bananas.
Snow White and forest animal friends
Dress your young twins up as forest animals while the big sister is Snow White!

Brave's Merida and Baby Bear Sister

With the older sister dressed as the spunky Merida, the younger sister or sisters will look adorable in a bear suit! Great for multiple younger siblings, and the adults can dress as the Scottish king and queen. Don't forget about the big mama bear!

Monkey and Banana Sister Costumes

An adorable monkey with her favorite fruit will bring many smiles! Remember to tell the sister who dresses as the monkey: No biting!

This costume works great for a big sister with multiple younger siblings. The little ones can go as a bunch of bananas! Even baby can get in on the act, dressed in a banana bunting suit.

Snow White and Sister Costume

If your older girl wants to dress up as Snow White, you could always dress up one of your little girls like one of the dwarfs, but I think it would be cuter to dress the little one as one of her adorable baby forest friends!

Also a great idea for multiple younger siblings: try squirrels, raccoon, and deer!

Costumes for Sisters and Babies

Alice and the White Rabbit
Cookie Monster and Elmo
Butterfly and caterpillar

Alice and the White Rabbit

This beloved tale offers fantastic costume options.

  • An older girl can dress as Alice while her little sister dresses up in a white rabbit costume.
  • The older girl is Alice and the younger sister is the Cheshire Cat.
  • Twin sisters can dress as Alice and the Queen of Hearts.

The Cookie Monster and Elmo

You may think only boys can dress as Elmo and Cookie, but girls can enjoy dressing as their favorite friendly monsters too! If your girls like frilly dresses, try these super girly-girl monster costumes. Otherwise, they can wear the same furry red and blue suits that the boys wear!

Butterfly and Caterpillar Sister Costumes

A great costume idea for a big girl and baby sister, the butterfly and caterpillar are lots of fun for big sister, who can choose which type of butterfly she wants to be. Monarchs, of course, are right in season with their orange and black coloring.

Costumes for Older Kid Sisters

Daphne and Velma
From Scooby Doo
Tiana and Frog
From The Princess and the Frog
Ariel and Melody
From The Little Mermaid
Odette and a swan
From Swan Lake
Angel and devil

Daphne and Velma Sister Costumes

This pair of teen detectives from Scooby Doo have unmistakable looks that make for great sister costumes. Other siblings or friends can make up the rest of the gang by dressing up as Scooby, Shaggy, or Fred.

Costumes for Adult Sisters

Taco sauce packets
One spicy and one mild!
Simple, with round white wheel on tummy!
Marge Simpson's sisters
Patty and Selma
Toothbrush and toothpaste

      Really? Many of these women still look really good in their \ young\ pcuetris, and most of the ones who don\'t look good look that way because very few people would apply the label \ sexy\ to an 8 year-old.
