Rosalina appears as a tall 7 ft youthful woman with blue eyes and light blond hair with a large bang obscuring her right eye. Rosalina wears an aqua floor-length dress which bares her shoulders, where a powder-blue flap loops around, and has long flared sleeves, topped with powder-blue frill. She often floats and is like a mother to Lumas.

Lumas are cute little star shape creatures that floats around and can shoot star bits. 

Rosalina wears a silver crown and carry a silver star wand
