Looking at Mon’s Angua sketch (sorry, Mon, I pestered Alicey until she showed it to me. She was being good), I realize that nowhere in the books does it imply that she wears a skirt, as far as I can remember. There might be something buried in Feet of Clay, but nothing came up when I ran a search through my e-texts. I have been corrupted by fanartists! I see no reason why she wouldn’t wear the knee-shorts all the other Watchmen wear. Wow. Revelation.
