One reason for the "casualization" of dress were the world wars. Rationing and general mood (and having your country ripped apart) made it kinda impossible to dress extragantantly as a rule anymore. After the war ended, it kinda stuck (just like the daily shaving thing).

That sure sounds plausible, but is there any evidence that this was actually the case? I'm always looking for excuses to dress extravagantly and not shave.
