Passage: An extensive wardrobe was designed for Padmé Amidala by Lucasfilm concept artists and costume designers. Like Leia Organa, one of the inspirations for Padmé was the Flash Gordon character Dale Arden. The wardrobe in The Phantom Menace was designed by concept artist Iain McCaig and costume designer Trisha Biggar; concept artist Dermot Power joined McCaig and Biggar in the design process of Attack of the Clones. Biggar worked as costume designer on the three films. Many costumes were inspired by the historical royal fashions of different cultures. For example, in The Phantom Menace, the dress which Padmé wears when addressing the Senate is based on Mongolian imperial fashion worn by Empress Dondogdulam, the wife of Bogd Khan, and other monarchs into the early 20th century. Padmé's travel dress in Attack of the Clones is based on 17th-century Russian fashion photographed on Grand Duchess Xenia Alexandrovna at the Romanov Anniversary Ball in 1903.The costumes of the prequel trilogy are purposefully more elaborate than those of the original trilogy. Lucas asserts that galactic society in the prequels is much more sophisticated. Commenting on the disparities between the two trilogies, Carrie Fisher mused, "Harrison Ford wears the same outfit for three flicks, and I was complaining that I wear, like, six outfits. And my mother – Natalie Portman – she wears three million. She walks through a doorway and there's another outfit. It's like the Liberace of sci-fi changing of clothes." Trisha Biggar reveals that originally there were only three costumes planned for Amidala in The Phantom Menace, but "[Lucas] decided that every time we saw [her] she was going to have a different costume." Lucas explains, "Someone of that stature would automatically be changing their costumes to fit the occasion."
