Despite the increasing amounts of finery in Kate's closet, the High Street Duchess is still (just about) visible, and she has also worn a handful of lower price point items in the past year. The cheapest was the $35 Jigsaw faux fur wrap that she chose for the queen's annual festive lunch. Kate has had the piece for many years, and also brought it out for the same event in 2016.
Kate's other High Street item for the 2017 luncheon was a $146 black Zara cape - she also wore it for a performance of the Nutcracker in the same week.
