Padmé wearing the dress.
The parade gown is a specific attire that was donned by Queen Padmé Amidala during the celebratory events marking the conclusion of the Naboo Crisis, a time when Naboo gained its freedom from the Trade Federation's invasion in 32 BBY.
Following the Trade Federation's defeat and Naboo's subsequent liberation, a grand celebration unfolded outside Theed Royal Palace, an event graced by Queen Amidala. For this joyous occasion, she chose to wear a radiant, light pink ceremonial dress. This elegant, silken garment featured a banner-like adornment that gracefully descended from its low neckline. Enhancing this ensemble, she wore a cape embellished with a multitude of pink silken petals. The design of these petals was inspired by flowers native to Padmé's home village, which remarkably bloom only once every eighty-eight years, symbolizing a period of exceptional festivity. Completing the pink-petaled cape and long white dress was an ornate fan, finished with jeweled finials, a common element representing continuity in traditional Naboo fashion. She also wore a delicate royal diadem, and, for simplicity, wore minimal jewelry. Her hair was styled into a distinctive bun, featuring five crescents arranged in a star pattern at the back of her head, and she completed her look with small, white, pointed shoes. The simple white dress showcased the pure joy of her and her people at Naboo's newfound peace.
This parade gown was originally designed for the 1999 film Star Wars: Episode I The Phantom Menace, which is part of the prequel trilogy. The final version of the costume was the work of costume designer Trisha Biggar and her team.
