Last summer, I had dinner with a dozen British and Italian insurance managers in Rome. In desultory fashion, we discussed the weather (hot) and the economy (not so hot) until someone raised the subject of socks. Suddenly the evening sprang to life: the men pushed their chairs back from the table and rolled up their trouser legs. Each British man was wearing a low sock that ended three or four inches above the ankle, revealing a quantity of snow white leg; each Italian had his calf covered in a finely spun sock that went all the way up to the knee. Each nationality stared at the other’s socks in uncomprehending horror.

I thought of these insurance experts the other day when I read a New York Times blog in which a fashion writer advised men what to wear on the day they get the sack.
