Yeah, um, that would be decades of various sumptuary-control laws against flashy clothing, the development of better handguns (making it so you don't want to stand out like a freaking songbird), various religious reformations and splinter groups (mostly this, really), and the industrial revolution (wherein clothing became 'off the rack' instead of tailor made for 99% of people).
Sometime in the past, I developed a liking for really bad dad-jokes... Mainly for the effect that they have on my wife and friends (physical pain results!), these are some not so bad ones I saw recently.
