The last thing she is ever seen wearing. She and the dress are so beyond beautiful. She looks like an angel almost. The dress looks like she’s wearing a waterfall, and all those sequins catch the light in such a sparkling way. The flowers in her hair are beautiful too, looking almost like stars. The flowers and resemblance of water seem to represent the natural world, and is a stark contrast to what Anakin has become. Vader’s costume is dark, cold, and terrifying. He is a man-made machine, nearly devoid of life, where as Padme seems to represent things that grow and give life, despite the fact that she is the one that has died.
The designer, Trisha Biggar, said the costume was meant to resemble the lakes of Naboo and symbolize her spiritual return to the lake. Natalie Portman once said the dress reminded her of Ophelia in that Padme looks like she’s drowning. I think these are interesting ways to interpret the dress. And I’m so glad they decided to include the japor snippet, calling back to her love for who Anakin once was.
