You could wear an ugly sweater to mark the festive season, or you could make like Kate Middleton and make a nod to the Yuletide in a super subtle, super chic way. 

The Duchess went to a Christmas party this morning (flanked by Harry and Wills) in what we think is a Vanessa Seward frock currently in the sale on Net-a-Porter. The red-and-green floral is plenty festive without involving light up twinkle lights and / or Santa’s face.
