Why do people say "dress like the job you want, not the job you've got"?

Question

Why do people say "dress like the job you want, not the job you've got"?

Answer 1

Thats similar to the saying "dress for success"

It means dress better than your boss. Impress people with your professional appearance. It can also extend into mannerisms, such as be as professional as possible at all times.

If people think you're important, they will treat you like you are. If people think you're successful, they will help you get where you want to go. It's a trick, people are suckers, use it to your advantage.
