It's always hard to figure out what kind of costume you want to wear for Halloween. It's even harder to find out what kind of costume you and your squad want to coordinate to wear for Halloween. Here are some of the best, and cheapest, costumes for your squad to wear while having fun during the Halloween Festivities.

1. Ninja Turtles: Everybody has seen "TMNT" at least once. It's a great costume for a group of four. Everybody picks the color they want to be and—voila—there you go. The squad rolls up and nobody will want to mess with you guys.

2. Power Rangers: Everybody wanted to be a Power Ranger when they younger. Well, now is the time to get your squad together and everybody can be the Power Ranger they never were.

3. The Kardashians: I love the Kardashians, and dressing up as them would be a great way to either make fun of this reality star family or embrace your inner Kardashian self.

4. Scooby-Doo Crew: You can never go wrong with the Scooby-Doo Crew. It's a pure classic, and everybody will recognize you guys as soon as you walk through the door.

5. Magic School Bus Crew: The magic school bus used to be "the show" back in the day. Rolling up to the party as the Magic School Bus Crew will bring back so many memories for everybody.

6. The Purge: Everybody has seen "The Purge" and has been scared to death while watching. Now, all your crew has to do is go buy masks and weapons, and walk around scaring everybody. It's the perfect costume if you want to be that terrifying squad.

7. Shark Week: Everybody is obsessed with Discovery Channel when Shark Week comes on. What better than to turn the whole squad into sharks and shut the party down?
