Many favorite Halloween costumes have been derived from the Star Wars movies. Princess Leia is one of the popular Halloween costume for adults as well as kids.
In "Star Wars" series, Princess Leia was the one of the rebel alliance’s greatest leaders to Restore the Republic, a former member of the Imperial Senate, and a member of the Royal Family of Alderaan. It was common knowledge throughout the court that Leia was adopted into the Royal Family. What wasn't common knowledge was that Leia was born to Anakin Skywalker, a Jedi pupil who succumbed to the dark side and became Darth Vader. She was one of a set of twins, born in secrecy and protected from Vader and the Emperor. The Jedi hero and general, Obi-Wan Kenobi, saw to it that Leia was secretly transported to the planet Alderaan, where she was to be raised by Kenobi's friend Bail Organa. The boy, Luke, was taken to the distant world of Tatooine. Leia has few memories of her true mother, Padmé Amidala. All that Leia can recall was that she was beautiful, but sad.
Leia was a driven, dedicated individual. She has a forceful, abrasive personality. She was professional in all aspects, but occasionally relaxed her guard to let her strong compassion and quirky sense of humor show.
Leia was played by Carrie Frances Fisher in the original Star Wars trilogy (1977–83) and Star Wars: The Force Awakens (2015). She was a petite, fair-skinned human female with brown eyes, and long brown hair that she often wears in an elaborate fashion.
