FWIW (not at ALL claiming that this "proves" me right in any sense), I am basically repeating the Flusser orthodoxy, as described by Manton (and Manton does go on to give an ambivalent opinion on Flusser's advice) in this post:
To flesh out a bit more - I don't think Chris's combo looks terrible. But I think the tie pattern looks kind of big and garish on top of the smaller scaled stripes. Wider spaced stripes would bring the two more into balance so the dots on the tie wouldn't look so big. It helps Chris that his stripes are a tad darker and wider than zbromer's, or at least it seems so to me from the pics, but I think wider spacing would improve things further.
When patterns are different (lines vs neat) I like scale to have less contrast. Compare to zbromers where similar shirt is next to smaller scaled tie

sorry, i dont see how this addresses addresses the small stripe/large neat, issue. am i missing something?
