I have always favored the Leather Domme look. I think the Mistresses of the 70s and 80s personify the powerful Leather Woman concept.

Standing before a cowering naked sub, completely encased in Leather is a feeling like none other.

I'm all for latex and lingerie, but nothing says Dominatrix like Leather!
