The only named female klingon in TOS was Cpt Kang's wife / science officer, Mara in "Day of the Dove". There were also several unnamed lady warriors in the background on that episode.
They all wore a mesh top and mini-skirt thing with black hose underneath, like THIS.
That top, skirt, and boots need to be added to the female clothing options. It wouldn't take much to add but it would go along way to introducing some variety to the KDF looks.
Yes yes yes yes YES! Did I mention YES? In fact HELL yes! Want!!!
I made a TOS Klingon with an Alien. From what I asked others, its pretty close to it. I don't have access to many pics of it right now and I'll post more later. They're a little small, bu tthats because I focused on the bridge of my ship.
