The Duchess of Edinburgh nailed workwear chic on Thursday when she stepped out to open the Domaine Evremond Winery in Kent.
Prince Edward's wife, 59, was seen at the new English sparking wine producer in Chilham near Canterbury wearing the stunning double-breasted grey blazer in a plaid print from Vince.

Sophie teamed the fitted garment with the matching wide-leg trousers in the same Italian wool blend. The outfit was elevated by the on-trend 'Ixia 80' burgundy patent pumps from Jimmy Choo with a kitten heel, as well as a duck egg blue silky shirt.
