I saw my first Utilikilts at the Renfest; black leather kilts with studded belts and "combat" boots not period but they fit into that whole scene. 'Cause the Renfest if for fun, food, laughs, and drinks.
Besides... Kilt....Green tights....Kilts....Green tights.... (despite the respect I have for Panache & Mr. Flynn) I'll take kilts any day over tights, even a "maroon" kilt.
