I think it's important to remember that the kilt evolved out of convenience. It has always been a casual, comfortable garment. It wasn't until very recently in history that it became acceptable to be kilted in a formal setting. The "small kilt" that most of us wear is a 16th century invention, and bears little resemblance to the "feile mor".

I have worn my kilt to fancy company Christmas dinners, and I will be kilted at my wedding. These occasions call for more than a T-shirt.

At the Scottish Games out here in California, where it can top 100 degrees, I'll stick with my day-wear attire. This usually consists of hose, flashes, 4 yard kilt, T-shirt and leather sporran.

In short, the rules of propriety change. It's no longer required at most businesses (even banks) for men to be wearing collared shirts with ties with slacks. I say dress to fit the occasion. You wouldn't be wearing a three-piece suit out here to the Pleasanton Fairgrounds. Neither will I wear a collared shirt and sweater to the same venue.
