Carbon Costume

Usagi is seen in the Princess Serenity in various points of the story, and in a fair amount of the manga art, she is seen with white hair, instead of her usual blonde, though her eyes remain the same blue.

For this outfit, she has a golden moon on her forehead instead of her usual Sailor Moon tiara, pearl stud earrings with a matching bracelet and hair pins, and a long, high waisted white dress, with intricate gold and pearl details, and swirled sleeves.
