Whether you love or hate it, dressing up is always more fun with a group. Finding a Halloween costume can sometimes feel like a burden, but if you grab two friends, it takes the stress off and adds a lot of fun. There are tons of Halloween costumes for three people out there, from classic movie trios like Harry, Ron, and Hermione to creative options such as Bed Bath & Beyond and funny moments from the past year (hello, Zoom screen.)

So, grab your friends, boo, or kids, and embrace Halloween costumes for three people. There will be no third wheels at this party.

Could there BE a better girl gang to impersonate for Halloween?

Any ’90s outfits will get the job done; just make sure to reflect Phoebe’s hippy energy, Rachel’s trendiness, and Monica’s classic looks.

3. Tequila shot ingredients

The key ingredients to a tequila shot? Lime, salt, and tequila. Make things simple with this no-fuss Halloween costume (and make sure to bring actual tequila to the party for an extra good time.)

4. Josie and the Pussycats

There are tons of iconic characters on The CW’s Riverdale, but the perfect group to dress up as is the girl band Josie and the Pussycats. All you need is some cheetah clothing, cat ears, and fake microphones to seal the deal.

10. Donna and the Dynamos

13. Mario, Luigi, and Princess Peach

Video game lovers, this one’s right up your alley. Channel your inner cartoon character and dress up as the famous Mario, Luigi, and Princess Peach from Mario Kart. (This one makes a great family Halloween costume, too.)

Grab your girl gang and fight over who’s who of the Sex and the City women. Although this would typically be ideal for four friends, with Kim Cattrall not reprising her role as Samantha Jones in the HBO reboot, Charlotte, Carrie, and Samantha make the perfect Halloween costume for three people. A tailored sundress and pearls will perfectly capture Charlotte York, a blazer and slacks will represent Miranda Hobbes, and pretty much any trendy outfit will encapsulate Carrie Bradshaw (but mismatched stilettos are an obvious choice).

16. The Incredibles

The Incredibles is one of those animated movies we’ll proudly declare our love for, no matter how old we get. If you feel like showing off your curves in a latex suit this Halloween, go as Elastigirl or Violet. Make it a family affair with other members of the Incredibles gang.

17. Bed, Bath, and Beyond

Now, this is creative. If you like funny Halloween costumes that surprise people, opt for bringing the store Bed Bath & Beyond to life in a Halloween costume for three people. Whoever represents “bed” gets to wear their PJs, the “bath” representative wears a robe, and “beyond” channels their inner space cadet.

18. ‘The Wizard of Oz’ characters

The Wizard of Oz is one of the most classic movies of all time, and it’s chock-full of fun characters to dress up as for Halloween. The staple choices are Dorthy, Glinda the Good Witch, and the Wicked Witch, but you can also choose between the scarecrow, lion, and Tin Man.
