For an outing earlier today with husband Prince William, Kate Middleton showed off one of those British style classics we've come to love her for: the coat dress. Hers was by Orla Kiely (and she wore it back in February 2012, too!). Across-the-pond style setters like Kate wear the piece a lot, though it's less familiar stateside. Done in a heavy fabric like jacquard, it fits like a dress with the weight of a topper so it's comfortable to go sans coat. We love the sophisticated, ladylike style as a fresh option for holiday parties. Curious? Shop some below!
