I was watching the episode of "Home Improvement" that had Tim and Al wearing kilts for most of the show. I'd just had a shower and was in my housecoat. For some reason I made a connection...my housecoat was the most comfortable thing I owned to lounge around the house in. Perhaps a kilt would be just as comfortable.
The rest is history, although I'm still not at the point of wearing my kilts out in public as much as I'd like.
