Anna Wintour might be at the helm of a brand that celebrates new trends every month, but when it comes to her own wardrobe, she is a strong believer in adopting a uniform and sticking to it for decades. This is the woman who only seemed to pack one pair of boots for fashion week and is the only person who makes it easy to predict what she will wear to the Met Gala regardless of the theme (Chanel. Always Chanel).

This summer, she has been leaning on her "power triangle"—a pair of nude Manolo Blahnik sandals she has been wearing since at least 2011, bright painterly florals (Marni is one of her go-to labels), and her colorful gem necklace that is as much a permanent fixture as her signature blackout sunglasses. Sticking to signature pieces like this not only makes getting dressed in the morning much easier, but it helps you define a personal style. Keep scrolling to see how Anna has worn this "summer uniform" over the past few weeks and to shop her power triangle.
