The Best Group Halloween Costumes for Siblings

Group Halloween costumes are fun, but they're even more amazing when your siblings are involved.

If you're all about dressing up with your fam, we've got nine solid sibling group costume ideas for you to choose from.

Round up your siblings and scroll through the list below to agree on the perfect getup.

Phineas and Ferb

Dressing up as Phineas, Ferb and Candace from Disney Channel's Phineas and Ferb makes for an ace group costume. Everyone will instantly recognize who you are, but you'll have to make sure to stay close by to one another. No one will really be able to tell who you are as individuals, unless they're massive fans of the show.


The Goonies

The Goonies is an '80s classic that even inspired Stranger Things. The movie is so iconic, so if you haven't seen it, you need to. Luckily, recreating these costumes is pretty simple, seeing as the characters wear regular clothes. Which character will you be?


Circus Folk

This one would be a great costume for the whole family (pets included), because what family isn't like a circus already? It'll definitely take a bit of work to pull off something as elaborate as the example below, but you can keep your costume much more minimal. It's all up to you!

Dexter and Dee Dee

Two of the most recognizable siblings of all time are Dexter and Dee Dee from the cartoon Dexter's Laboratory. For Dee Dee, all you need to wear is a pink dress, pink tutu and ballet shoes. For Dexter, throw on a lab coat, some glasses and purple gloves.

Sanderson Sisters

Sure, everyone will be dressing up as the Sanderson Sisters from Hocus Pocus, but only you will actually be doing it with your siblings. Get your witch on!

Ariel and Her Sisters

Everyone loves Ariel from The Little Mermaid, but we often forget she had some pretty amazing sisters by her side. Remind everyone of this by going as Attina, Alana, Adella, Aquata, Arista, Andrina and Ariel for Halloween this year.


Weasley Siblings

If you're a Harry Potter fan, you definitely need to convince your siblings to dress up with you as the Weasley bunch. What costume could be better?



Okay, hear us out. Minions are totally annoying, but they're also kind of cute. Plus, it's incredibly easy to be a minion. All you need are some goggles, a yellow top, gloves and overalls.

The Kardashians

You can be anything you want on Halloween. So if you've always dreamed of being a Kardashian or a Jenner, now's your chance. Have your siblings join in on the fun for the full effect.
