29 Pop Culture Halloween Costumes Perfect For Brothers

Updated on 9/27/2023 at 12:30 PM

Group costumes are always going to be our favorite Halloween costumes, and this Halloween season, we want to a shine a light on costumes that would be perfect for brothers. From real-life siblings to fictional ones, from iconic TV cousins to groups of best friends, these are the ideal costume choices for sets of brothers (though siblings of other genders can find some majorly fun inspo here too).

As for the costumes, there's, of course, perhaps the world's most famous brother duo, Mario and Luigi, who had a major year thanks to the "Super Mario Bros. Movie" this spring. There are quite a few sets of brothers from the worlds of "Game of Thrones" and "House of the Dragon" if you want to aim for costumes that are a little more hardcore. Or keep things more grounded and channel our favorite pair of cousins — Carmy and Richie from "The Bear." You could also throw it way back and channel some brothers from "Supernatural," "One Tree Hill," or "The Goonies."

Whatever you choose, these ideas can help you have the best Halloween ever — whether you spend it surrounded by family or with friends. Ahead, these are 29 Halloween costume ideas for brothers.

Connect 3 in "Camp Rock"

Steve and Doug Butabi From "A Night at the Roxbury"

What to wear: Black shirts under satin suits (burgundy for Steve, blue for Doug) and a single silver chain.
How to act: Go up to people and try to dance with them simultaneously. Nod your heads a lot to the beat of the music.

Robb Stark, Jon Snow, and Bran Stark From "Game of Thrones"

What to wear: Lots of burlap and leather in brown, earthy tones. Swords are the perfect prop.

Tyrion and Jaime Lannister From "Game of Thrones"

What to wear: More brown leather, but for Jaime, you'll need a chest plate, a cape, and a golden glove for his hand.
How to act: Tyrion is witty and seldom sober; Jaime is also quick-witted, but a skilled fighter as well.

Lucas and Nathan Scott From "One Tree Hill"

What to wear: Lucas generally just wears jeans and a T-shirt, and if you're Nate, you may as well toss on a basketball jersey.

What to wear: Red track suits.

How to act: You're both psychiatrists, so start analyzing everyone around you until they get annoyed.

How to act: Like the world's silliest fast food employees.

The Mandalorian and Grogu From "The Mandalorian"

What to wear: For the Mandalorian (aka Din Djarin), you need a Mandalorian suit complete with a mask (but we won't tell if you take it off sometimes). For Grogu, you need the classic Yoda ears and a brown robe.
How to act: This is a particularly good costume for brothers with a big age gap. As Din, you're very protective of Grogu, while Grogu is a mischief maker (who wants to eat all the Halloween candy).

What to wear: For Carmy, wear a white tee shirt and a blue apron. Richie, meanwhile, opts for a navy-blue "Beef" shirt and a khaki half apron.

The AFC Richmond Coaches From "Ted Lasso"

What to wear: AFC Richmond track jackets, whistles, and fake facial hair if you can't grow your own.
How to act: Like you know a lot about soccer — err, football — but you also have a heart of gold.

King Viserys and Prince Daemon From "House of the Dragon"
