1. James P. Sullivan and Boo.

Are you and your significant other looking for a couples costume this year? This one is super easy and adorable!

2. Gumball machine.

Throw on some red bottoms, hot glue pom-poms to a white t-shirt, make a "25 cents" belt out of felt fabric, and you're ready to go!

3. "When life gives you lemons..."

This DIY costume just consists of writing "LIFE" on an old t-shirt and carrying around a bag of lemons. It's super simple, yet unique and funny!

4. Deer hunter.

Do you own a lot of camouflage clothing? Don't spend too much time stressing about your costume -- go as a deer hunter! You just might even find someone to dress up like your deer!

5. Starbucks Cup.

All you need is a white dress and a brown paper bag to make this costume! You can either draw on the classic mermaid logo or print it out to make your costume complete.

6. Cactus.

A green dress, hot-glued-on pipe cleaners, a witty saying, and a hair flower = a clever last-minute costume!

7. Emojis.

Looking for a group costume? This one is perfect! Just use some yellow poster boards, construction paper, and sticks to create your Emoji-faces. Have your group dress up in all black while carrying the Emojis and you'll walk into the party looking like you've been planning out the costume for weeks.

8. The "Cat Lady."

Although this costume is shown on a child, I think it would be super hilarious on an adult. You'd be both comfortable AND have a ton of fun laughing at how ridiculous you probably look.

9. Pineapple.

Already have a yellow dress? Perfect! All you'll need to do is make some sort of pineapple-like headwear and you're good to go.
