Make fun of Donald Trump’s comb-over all you want, but his hair is an important part of his brand and gives him a distinctive visual identity like Hillary Clinton’s colorful pants suits.
Developing a signature item or style as a trademark of your visual style is a great tactic for personal branding. You’re creating a branding element that identifies you, like the logo on a product.
You can also build your career identity around particular accomplishments and experience like Clinton does with her political experience or Trump does with his business success.
It’s also smart to think in terms of creating intellectual property, ideas that people associate with you like Bernie Sanders has done around the issue of income equality.
