When I was 18, I got my first job in fashion. Within days, I discovered a uniform worn by the industry’s most successful, most important women. The uniform she wears when she’s become her own boss and must confidently and comfortably lead a troop of her miniatures. She, in my experience, was the stylist Kate Young, who showed me the way when walking into the office wearing a faded heather-gray sweatshirt and a Cartier tennis bracelet she’d just bought herself. No matter how well groomed or well-off her team was, there was no doubt: she was the boss.

Nothing, and I mean nothing, screams power more than a makeup-less woman with neat, air-dried hair wearing suit pants, flats, a sweatshirt, and a sprinkle of ice. The combination amplifies the sweatshirt’s casual cool and the diamond’s luxurious elegance, all while creating a look you can actually work in.
