Diana Vreeland steered the course of mid-20th-century style, serving as fashion editor at “Harper’s Bazaar” and as the editor-in-chief of “Vogue” for a combined three decades. Known for favoring eccentric and standard-shattering looks, she never flagged in her love for fashion as an art form and lifestyle; she even curated exhibitions at New York’s Metropolitan Museum of Art well into her 70s. Vreeland truly lived out her own mantra, and encouraged others to do the same by cultivating the things that make us feel most alive.
