Costume help:: for four people to "go together"? - four person costume ideas

Ok, theres me and three other girls at the age of 16 years.

We want things to go together a little

namely, the Spice Girls (this thing a little vague, but not necessarily) a group, another idea we had was a person who jailbait, a police officer, child soldiers and firemen (with more girly clothes)

Ideas?
