When it comes to holiday party attire, there's a fine line between appropriately festive and cheesy, but leave it to Kate Middleton to nail the perfect Christmas outfit and be otherwise physically incapable of all sartorial cheesiness. The Duchess of Cambridge selected a red floral print silk jacquard dress courtesy of Vanessa Seward for a party benefitting volunteers at The Mix, an organization that provides an online safe space for under 25-year olds to seek answers to questions surrounding sexuality and relationships, housing, body issues, finances, substance control and employment. And if you're still looking for that perfect present-unwrapping, gingerbread-cookie-eating getup (and think you can wear it better than HRH), then you're in luck: The dress is currently on sale (!) at Net-a-Porter for £432. Pair it with simple black accessories à la K.Midd and you're good to go.
