DRAMA PERFORMANCE - costumes?

My drama performance is nxt week and we are gonna have grades given for it. I am quite confident that i will get an A becoz evry1 tells me i am a star at the end of each practise in the lessons. I play many different characters such as : a gay french director, a baliff, a shopkeeper, a customer for the phsychic job, and a guard. All my characters are Male so i was wandering what costumes i could use but not change too much, like soemthign that i can add or get rid of in order to represent my change in character bcoz i dont want a whole outfit for each , i wanna be able to change quickly. Any suggestions!?
