I was talking with a psychology teacher friend of my last night and told him that I was so used to wearing kilts that trousers now felt odd.

He replied that this was an example of habituation. In order to avoid over stimulus the brain "blanks out" constant stimuli and only looks for changes in stimuli. ( my words - his were fancier)

What this means in practice is that any new clothing will feel strange for a time but then we become used to it. I'm sure that you dedicated kilt wearers will attest to the fact that the kilt feels normal. Newbies often love their kilts but are not necessarily at home in them.

The down side is that getting the guy in the street into a kilt is not only socially difficult, he has to overcome habituation to trousers or jeans (I used to wear jeans a lot and thought them comfortable. Now I haven't worn jeans in 10 years and I find them dreadful)

Now going back to the change in stimulus; the kilt gives positives - the sway while walking for example, and the airiness. Trousers give negatives - chafing, hot and sticky in warm weather.

To sum up: the more you wear the kilt, the better it becomes
