Dinwiddie knows about coming out of nowhere. In 2012, she was writing a sharp-witted blog called “Trashy Beyoncé” in her grandma’s Chicago basement. A year later, she was a “strategy intern” at Wieden + Kennedy, where she caught the attention of senior copywriter Nathaniel Friedman. Friedman, a cult sports writer known as freedarko, helped convince her to become a copywriter. By 2017, Dinwiddie was the unlikely “influencer” on BET’s “25 people killing the shoe game” — an unknown, rising star copy writer in Portland, Oregon, parked somewhere between Michael Jordan and Rihanna.
