You've got to hand it to Kate Middleton: she really knows what she likes when it comes to style. The duchess is all for rewearing old favorites, shopping the same labels, and following tried-and-true outfit formulas. So when she decides to switch things up, there's likely a good reason.
During a visit to Stewards Academy, Kate opted to give a nod to NYFW, rocking American label Altuzarra for the first time. Although the brand — which recently revealed its stunning Spring '17 collection — is a new one for the royal, the blue, button-front, dotted design seemed just her style. Then Kate turned to side, revealing a bit of leg through a slit, and we realized this was no ordinary number.
Check out the modest yet subtly sexy piece ahead, and shop it for yourself before it sells out.
