According to Sabrina SSHEENA is Billy Wilder, is Fedora and Norma Desmond. She is not particularly affable, but when she passes you keep your eyes on her, at a safe distance.

She has lacquered nails. A cat. Pearls. He also wears jeans. It is also probably Joan Crawford. "I am convinced that a designer should be at least a half decent tailor.
