Her primary outfit consists of a turquoise long-sleeved gown that bares her shoulders, along with a silver crown with four gems on it, a sliver star-shaped brooch, gold star-shaped earrings, and silver round toe high heels. While she was young, according to her storybook, her hair was something more like a red or strawberry-blonde, which had similarly happened to Peach due to NES limitations. She has peach-colored defined lips, and long platinum-blonde hair that reaches to her waist. Rosalina is a very tall woman with cyan colored eyes, with only her left eye visible from a directly frontal view as her particularly large bang of her hair hides her right eye. Rosalina possesses extensive knowledge of the universe and the abilities of the Lumas, as she explains to Mario/Luigi how Lumas transform into a plethora of things and how they are reborn. She also uses the phrase "may the stars shine down on you" as a way of saying "good luck." She also showed sorrow for her own mother, who apparently died many years before Rosalina met the Lumas. She is a loving mother figure to the Lumas, caring for her children diligently.
Rosalina is shown to be a wise, mature, motherly and kind woman, who has made protecting the cosmos her mission in life. 3.3 Super Mario 3D World/Super Mario 3D World + Bowser's Fury.
