With parties galore, what a perfect time to get together with all your buddies and celebrate. HalloweenCostumes.com has a great selection of costumes for groups of all sizes.

You can dress as fan favorites like Darth Vader, Princess Leia, or even Stormtroopers. Another option would be to have half your group of friends dress in Jedi robes and the other half in Sith robes and have one epic lightsaber battle!

4. Food Costumes for Large Groups
| Pumpkin Pie | Salad | Chicken Nuggets | Onion |

Food costumes are a great idea for groups with a bunch of couples. With so many solid combinations like milk & cookies, peanut butter & jelly, and wine & cheese among others, it's easy to "pear" up your favorites (sorry, we love puns here). That's not to say you have to wear matching costumes all the time. If everyone in your food group costume is going as fruit and you want to be a hot dog, go for it! However, we recommend putting the costume on after driving to the party for the sake of comfort in your vehicle.

A large group of pirate costumes is perfect for events like Halloween, Renaissance Faires, and even the Gasparilla Pirate Festival. However, if you do choose a large pirate group costume, please don't do any pillaging on Halloween. People don't like that.
