There’s no denying Kate Middleton is a fashion icon. There’s a study about it for Pete’s sake. And while she’s been known to set trends, her most recent au-courant contribution was truly forward thinking. 

It was January 30 in Stockholm, Sweden, when the 36-year-old royal mom arrived at the home of the British Ambassador to Sweden wearing a deep yellow gold floral Erdem dress.

It was off-brand for the Duchess of Cambridge, who normally sticks to rich blues and prints of the tartan or polka-dot variety. But that’s not all: It appears that K-Middy was wearing the color of fall way before fall trends had even crossed our mind.

It didn’t take long for stars of a sartorial mindset to catch on. Other celebs started copying Kate in late spring, and by the first sign of autumn, yellow was everywhere.
