Scarlet has an elegant and deceptively ordinary appearance, with long black hair streaked with red and tied neatly into a ponytail. A prominent scar crosses the left side of her face, leaving one eye permanently discolored white, while her other eye is dark and difficult to read. She wears a deep red blouse with its sleeves rolled to the elbows, decorated with golden buttons and subtle gold accents around the collar. Matching golden ball earrings and a black belt with a triangular golden buckle that defines her waist. A simple black A-line skirt, dark pantyhose and black pumps complete her outfit, giving Scarlet the polished appearance of an ordinary office worker rather than a renowned assassin.
