Kate Middleton joined Prince William and Prince Harry to celebrate World Mental Health Day [1], and she chose quite the refreshing look. No, it's not just because there's a blushing bouquet of flowers printed on her chiffon piece. This is the first time the duchess has worn a dress by Kate Spade New York, and it likely won't be the last. Kate styled the chiffon design just as we'd expect, with a modest pussy bow secured at the neck (though the sash is removable and can also be tied around the waist).

Kate went for the fancier update, however, accessorizing with suede Gianvito Rossi pumps, her L.K. Bennett clutch, Kiki McDonough diamond drop earrings, and her sapphire engagement ring, an eye-catching contrast. Our favorite detail about this outfit, however, is the pattern on her fit-and-flare, which, according to Kate Spade's site [2], is "inspired by the roses tossed on stage at the end of a show." Isn't that lovely? Read on for a closer look at the duchess's ensemble, then shop her versatile dress along with a slightly different silhouette, if you prefer shorter sleeves.
