Carrie Fisher was undoubtedly the lifeblood that made Leia so special on-screen, so it should come as little surprise that, like her counterpart, Fisher became known as being a bit rebellious. Her wit and resistance to being dubbed a sexpot was also a mainstay of her post-Star Wars fame, and she was particularly outspoken about the challenges of some of Leia's costumes.
For example, Fisher revealed in her comedic stand-up special-turned-memoir Wishful Drinking that Lucas instructed her not to wear a bra under her infamous white dress because, to his mind, women in space wouldn't wear underwear for fear that they'd be strangled in zero gravity situations. "I want it reported that I drowned in moonlight, strangled by my own bra," she joked of the odd logic.
The infamous gold bikini Leia wore while imprisoned by Jabba the Hutt during Return of the Jedi was also a subject of some discord with Fisher, who kindly advised The Force Awakens actress Daisy Ridley to resist a similar fate. However, Fisher ultimately made peace with the costume by creating her own backstory for the look; in response to a citizen movement to have "slave Leia" removed from Star Wars merchandise, she told The Wall Street Journal, "[to] the father who flipped out about it, 'What am I going to tell my kid about why she's in that outfit?' Tell them that a giant slug captured me and forced me to wear that stupid outfit, and then I killed him because I didn't like it. And then I took it off. Backstage."
