Halloween and Family Weekend may fall on the same day this year, but have no fear because everyone knows three’s a party. With any of these costumes, you and the rents are a shoo-in for best trio no matter where you end up the night of Oct. 31.

1. Harry, Ron and Hermione from “Harry Potter”

The classic trifecta of wiz kids is a no-brainer for three-person costumes this Halloween and Family Weekend. Throw on some robes, grab your wands and say “Expecto patronum!” to any haters.

2. Minions from “Despicable Me”

Needed: Three pairs of goggles, overalls and gloves. Done. Boom.

3. Owen and his raptors from “Jurassic World”

Take a hint from the summer’s blockbuster and channel your inner dinosaur this All Hollow’s Eve. Sure, being Owen will be great. But being a raptor? Even better.

4. Rock, paper, scissors

Want to save money this Halloween? Opt for do-it-yourself costumes rather than pre-made ones. Check out this easy, step-by-step tutorial for the timeless hand game on Lauren Conrad’s blog.

5. Snap, Crackle and Pop

These totally underrated little fellows are sure to be a hit at any costume contest this Halloween. Bonus: Dress up as the three elfin brothers and you get to carry cereal around with you all night, so you’ll be totally prepared no matter where or when the munchies hit.

6. Spoon, fork and knife

Who says cutlery can’t make great costumes? Plus, this triad of outfits also pairs well with snacks.

7. The lion, the witch and the wardrobe from “The Chronicles of Narnia”

Return to Narnia, my friends.

8. The primary colors

Literally just wear all red, blue or yellow. It doesn’t get much simpler and effortless than this. (And you thought the minion costumes were easy!)

9. Three blind mice

The beloved three blind mice are another great DIY costume option. So go ahead, rock your sunglasses at night.

10. Three little pigs

Y’all ain’t afraid of no ghost big bad wolf.
