My grandfather Bob Scott never displayed the slightest interest in a kilt to me while he and I were both alive.

However, if grandpa was going to bother wearing a necktie he would by God wear a red one. He was very good at dressing down to go fishing, adept at dressing more or less invisibly most of the time; but when he dressed up the man was dressed to the nines.

I still struggle with the idea of "smart casual".
