Have you met the world's richest man, Elon Musk? Tell him about your dress code and its relationship to success. I'll promote the person on my team that writes the best code, not the one who has nicely pressed slacks. Similarly, I'll vote for a lawmaker who represents me and gets things done, and I don't give even one damn about what they are wearing or what they had for breakfast, even if it is the most important meal of the day. Otherwise you are a lousy leader, if you care about appearance more than results, and I wouldn't want to work for you anyway.
