Jester, I defer to your much greater knowledge regarding the rules. However, I personally would be more concerned about aesthetics. If some of Don's previously-posted trousers have obeyed the rules, but in doing so have been less flattering to his legs than the pair above, then I'd recommend that he break the rules.
Speaking of which, is there a single thread or FAQ on this site which states what all "the rules" are? I would certainly like to know more about them than I currently do.
Not really- there's a 'non-rule rule' thread that's useful, and Whnays Good Taste is worth a read from start to finish- Foo's at his most informative brutal best about half way thru, and altho his word's not gospel on jacket - shirt - tie - square combos there's few that justify their choices more clearly. His reasoning might be something to bounce your own ideas off. Particular posters are probably more useful than particular threads- Manton of course, and Foo, Dopey and Vox cover everything at some point. No offence to anyone I've left out.
