I see the appeal of a personal uniform. Like a cartoon character who wears the same outfit every day. You'd never have to go clothes shopping and you'd have one less thing to worry about in the morning before work. And assuming you choose the right combo you'd know you were always looking your best.
Aaron Brown did this. In 2002 he had 7 black t-shirts and every Sunday he washed his one pair of khaki trousers. He swore by it.
