Possibly subverted in Redwall; on one occasion the Big Bad Badrang cuts a random minion's belt when he finds himself in need of a piece of cord, and everyone sniggers when said minion's kilt drops off. On two occasions, prisoners have suffered a Shameful Strip, which presumably wouldn't matter if they didn't consider clothing important in some way. In contrast, the cartoon show followed this trope; as well as most of the characters only wearing shirts, it showed Skalrag wearing variously only a cloak or nothing at all, and unusually depicted the female character Trefoil with an unclothed lower half as well.
Now, to be fair, a kilt is a kilt. They have more things in common with habits and (naturally enough) skirts than with trousers.
