I am familiar with this armor. It is supposed to be a pair of pants (and the icon shows pants) but it has been bugged for years and shows the "underwear" skirt instead, with the main difference being that it is dyable. I think way back at the time when it was discovered it was determined to be a "bug" and I guess this one finally was grabbed from the massive bag of bugs on SSG's "bug fix Fridays", and some dev took some time to fix it and apply it to the patch.
I'm not so sure it should be reverted...... but I do agree that the game should have more skirt options, including good looking kilts.
