It's quite a challenge to search for the perfect costume for Halloween, and it's two times harder when you're looking for a couples' costume. Last minute decisions could end up in an argument with your significant other, so plan ahead! Take a look at the Halloween couple costumes suggestions below.

Sadness and Anger from "Inside Out." While not exactly a couple, these characters are from the highly talked about animated movie that came out this year and they're fairly relatable and recognizable to boot. This Instagram user has a simple but creative idea a wig, beanie, white shirts and neckties.

Kermit the Frog and Miss Piggy. They're back in the limelight, thanks to the revival of the TV show.  Some of things you'll need to pull off this costume include a sequined dress or red dress, pearl necklace, blonde wig, a pig snout and ears. You'll also need green body paint, a green collar and a frog mask, or have Kermit wear a tux with the mask and paint. Even better: switch up and let the guy be Miss Piggy.

The Lyons - Lucious and Cookie - from "Empire." They're the most popular couple on television right now. To dress up like the Lyons, go for "power looks" and think bold - lots of accessories, animal prints and furs, according to Who What Wear.

Peanut Butter and Jelly. What else could be more perfectly matched than this? You can purchase this costume here.

Scary Dead Kids. Go with a classic. (Who doesn't get freaked out by the twins in "The Shining?" It's a safe place here. You can admit it). And hey - those who scare together, stay together! Things you'll need: scary makeup, a dress or nightgown for her and a pair of pajamas for him. Bring toys for props, too! Take points from this couple on Instagram for some ideas.
