If you and your sibling were once womb-mates, it’s highly likely that your mom dressed you to match once in a while. (Read: EVERY. SINGLE. SATURDAY. For the weekly trip to Grandma’s house…even if you weren't identical…or the same gender.) You can’t really blame her; there are few things cuter than matching babies. By now, however, we’re going to guess that you’ve developed your own sense of style (entirely separate from your brother or sister). But when it comes to pulling off an impressive Halloween costume idea, twins have a built-in buddy—so why not grasp on to your lifelong wingman for the assist? What is bacon without eggs? Peanut butter without jelly? Maverick without Goose? Face it: You’re better together, and so are all of these twin costume ideas.
1. Mario and Luigi Costumes
|Adult Luigi Outfit||Adult Mario Costume||Boys' Luigi Costume||Boys' Mario Outfit|
Probably the most famous and enduring pair of twins of all time, the Mario Bros. is the perfect boys' twin costume idea. This Halloween costume idea works well for both identical and fraternal twin brothers, as Luigi is famously taller than his twin brother, Mario.
2. The Shining Twins Costume
|The Shining Grady Twins Costume||Black Baby Doll Heels||White Knee-High Stockings|
Anyone looking for creepy twin costumes should look no further than The Shining's Grady twins. Is there anything scarier than two dead little girls blocking your path down an empty hotel hallway? (The answer is no. Kids in horror movies are always really, really creepy.) After you get the Grady twin dresses, you'll need to add some knee-high white socks and black buckled shoes to finish your twin costume idea.

Many of our twin costume ideas so far have come from pop culture, but maybe that's not your thing.

Mike and Sulley from Monsters, Inc. certainly fill that niche. While they're not blood brothers, their teamwork is the stuff of legend at their workplace. They're generally a little on the "big and scary" side, (or at least one of them is), but how cute are they as twin baby costumes?
8. Mickey and Minnie Costumes
|Toddler Mickey Mouse Costume||Toddler Minnie Mouse Costume||Toddler Roadster Mickey Outfit||Toddler Roadster Minnie Outfit|

13. Tortoise and the Hare Costumes
|Adult Turtle Costume||Adult Bunny Suit||Baby Turtle Costume||Baby Pink Bunny Costume|

16. Jaime and Cersei Lannister Costumes

Certainly the most notorious pair of twins on this list, this Game of Thrones costume idea is not for the weak of heart.
