Peanut Butter & Jelly
A classic pair that everyone knows and loves—Peanut Butter and Jelly is the ultimate easy and cute costume idea. One of you wears all brown (think tan shirt and pants), while the other rocks a purple or red outfit to represent jelly.

Ghostbusters & a Ghost
Team up as a fearless ghost hunter and a mischievous ghost for a spooky-but-fun matching look. One of you can don a tan jumpsuit, boots, and a makeshift proton pack, while the other wears a flowy white sheet or a glam ghost dress with face paint and shimmer.
This costume is great if you want something a little creepy without going full horror. Plus, it gives each of you a distinct personality while still clearly being part of a themed pair. Expect lots of compliments—and maybe even a few ghostly photo ops.

Fire & Ice
Opposites attract in this striking fire-and-ice duo costume. One of you brings the heat with fiery reds, oranges, and yellows—maybe even a flame-print dress or a red wig. The other cools it down with icy blues, silvers, and shimmering accessories.
