If these same guys had rented tuxedos, they would have worn the trousers on their hips instead of at their waist. The problem is that most men don't know how to wear trousers, let alone the kilt. As far as wearing the kilt below the knee goes, well in my opinion that's when it starts to look like a "man skirt" instead of a kilt. How was it the venerable J. Charles Thompson described the look in "So You're Going To Wear The Kilt"? Oh yeah-- he called it "trollopy", which it most certainly is.
