It is to those I look to guide me in the prevention of embarrassing myself at function that requires proper dress (formal, semi-formal, etc) . The manner of dress and behavior during such functions is expected, nay, required. Now at the backyard BBQ, Neat and clean are really the only requirement, but I still have seen people cross the line. Lets face it, If i posted a picture of myself with a kilt inches above the knee, what would happen? Even at my backyard BBQ.
