We had a delightful lunch at the Spitfire Café with Pvt. Cheeseman of the Home Guard in full uniform, who talked about the notion that it is too uncomfortable to dress formally in hot weather being purely psychological. If it is part of what one Simply Does, the one simply does it and thinks no more about it.

I have always felt the same myself. After all, if bongos (as they probably soon will) considered it in order to walk the streets naked, they would be assuring us that they could not possibly submit to the mediaeval rigour of wearing any clothes at all in this hot weather. However, since they have not yet reached that stage they invariably wear some clothes (using the term "clothes" in the loosest possible sense) and consider it no great hardship.

I absolutely agree with this. I rarely wear short sleeves but when I do I don't notice that I am any cooler at all.
