Played by Heather Graham in the film Boogie Nights, Roller Girl was a '70s, x-rated film star whose gimmick was that of a sweet, non-so-innocent blonde sporting rollerskates and a '70s girl-next-door look. Mark Wahlberg's Dirk Diggler character may have been the star, but Roller Girl ended up as another memorable character in this cult favorite film. Put together your own Roller Girl costume with a '70s flavor and be the hit of your next costume party!
