3. Princess Leia's Slave Costume

Now this one is directed mainly at the men, and that's not to say you ladies can't also appreciate this one - the accessory in question is of course the costume that Leia is forced to wear when incarcerated by Jabba the Hut. The costume concept was initially due to the fact that Carrie Fisher complained she had no interesting costumes to wear in the previous films, so George Lucas requested this one. I'm sure I don't have to explain the reasons why this accessory is on the list, but let's just say it pleased many people when it appeared on the big screen, and its still giving fan-girls and fan-boys alike lots of entertainment The Star Wars wikia page had this to say:
Hundreds of female fans wear home-made and store-bought versions of the costume at science fiction conventions, many of whom post pictures of themselves on the popular fan-site Leias Metal Bikini
The costume has its own website, I mean, if that doesn't say how good it is, I dont know what will. For those interested,
you can buy it here.
