To call Kate Middleton a style icon is an understatement. She’s immune to flat winter hair, and even when she sports a butterfly clip, she looks posh. The Duchess always looks fabulous, even when she’s working out!

In fact, when she raced her husband, Prince William, and brother-in-law Prince Harry yesterday at a charity event, she nailed the athleisure trend. The race was to promote their Heads Together campaign for mental health at Queen Elizabeth Olympic Par. Instead of her usual uniform of skinny jeans, a blazer and wedges, Kate wore a pair of New Balance sneakers, stretchy leggings — gotta be able to move! — and a cherry red Perfect Moments puffer coat ($386). Mark our words: Like most things Kate touches, that coat is likely going to sell out fast.

Functional AND fashionable. We like it.
