LOL CD - never thought I would see a discourse in the WSJ on the matter and they show their age a bit with knickerbockers* and breeches showing up (clam diggers I have not heard of).
Is it you or PSD who hails from SF? - have you seen the Chubbies guys as mentioned ?

PS: Not so sure about the calf-length socks as mentioned in the comments and so many forget that the bush rangers in African game reserves have been setting the trend for bare legs for many many years anyway (just imagine telling those guys to wear boardies - let alone scaring to death the poor animals !)
