Stop the presses, Anna Wintour has made her Instagram debut. The Vogue Editor-in-Chief was snapped by photographer Taylor Jewell with her signature sunglasses and bob, reading the magazine's September issue. "Anna Wintour reads #TheSeptemberIssue. Do you? We would love to see it! Show us your #voguestagram." The fashion world responded to Wintour's trend, with the likes of Oscar de la Renta, Reese Witherspoon, and Calvin Klein's Francisco Costa all showing off their #voguestagrams.
