What are some good group Halloween costumes?

Ideally for 3 or 4 people. Everyone does thing 1 and 2, so thats a no. i did the four seasons last year. so somethin thats not cliche, but that people will be able to look at it know what we're dressed as. no book characters. i do not read. no horror movie people. no big mascot type costumes... so yeah. things a 13 year old girl would like. something that you could actually do easy.
