I doubt that few men's jackets, if any, would properly fit a member of the opposite sex. This one from Aero looks like it would fit the bill as a simple, understated Café Racer designed specifically for the female torso, although I imagine it would need to fit precisely in order to work, very much like the male Café Racer.
