An Official Alternate Costume for Rosalina starting in Mario Kart Wii, putting her in Biker Clothes.
She wears a White Jumpsuit with aqua/blue Under-Elbow Gloves and blue Knee Boots. She also has on a Blue Scarf, a Blue Belt, and her usual Star Brooch in the center. In Mario Kart World, due to it no longer being her default appearance when riding a bike, it became an obtainable costume under the name 'Aero'.
