which reminds me
Costumes of Padmé Amidala were largely inspired by historical royal fashions. Top: Grand Duchess Xenia, the eldest daughter of Emperor Alexander III of Russia and the sister of Nicholas II, photographed wearing a kokoshnik at the Romanov Anniversary Ball in 1903. Bottom: Mongolian royalty, before 1908. Source: Wikipedia, Wikimedia Commons (1, 2), Padawan’s Guide to Star Wars Costumes.
