What is it with British men in hot weather?

I was driving through town this afternoon, and as the traffic was queueing, I noticed what everybody was wearing on this beautiful sunny day. Most women looked smart, and as if they had dressed for the weather, but oh dear, the men. Some with no tops and their belly over their trousers, some with too tight nylon sports tops, some with what looked like their football shorts on with a long sleeved shirt. Suit wearers had taken their jackets and ties off, and had their long sleeved shirts loose. I didn’t see even one who looked half decent, no chinos, short sleeved shirts, tailored shorts, polo shirts, or sandals without socks to be seen. I think I live in a male style desert.
