Well, thank Oshikai for the spats. That was a clever concept. When loaded in their default state, they have a second "belt" positioned a little above the ankle, series of buttons and ship's insignia. I personally thought those details were a bit overkill, so I "blanked" them.
Oh, and here's a human variation upon the 'slacks" variation.
I labeled it as a "Cage" outfit, but with the more open black collar, it's more of a production era variation. I also used some actual pants geometry with flared hems that mimiced the men's uniforms.
