I second Black Lagoon.

Panty and Stocking. Although they are both fashionable I don't think either fit into the sterotypes of feminity. One is a sex addict and the other is a slightly quirkly gothish character.

Tenchi Muyo has Ryoko.

I agree that this is mostly the case in Hwang Mi-Ri works. Hot Blooded Woman is a fine example. However Boy of the female wolf is by Han Yu-Rang who has shades of this as well.
