When I first started, I thought a domme wore a black leather corset, fishnet stockings and thigh-high black leather high heel boots (above the elbow gloves optional). Her ad said Dominatrix and was called Mistress. At some point she struck a pose with her back to you and a horsewhip held below her derriere as she arched her back.

I was young then, put still think that Mistress when I hear DOMINATIX.
