So there's a party I'm going to and an obvious person for me to go as would be Cher from clueless but I'm looking for more original ideas, any famous 90's people??

you could go grunge and wear a plaid flannel shirt unbuttoned, high waist shorts, and some biker book like doc martens. a crop top with high waist shorts or any type of denim would work too. you could also wear a type of high waist skirt too with knee high socks and heels or jelly sandals. hope this gives you some ideas!!
