The Duchess is celebrating Valentine's Day with another royal engagement as she stepped out in London this morning for the second time this week.
Catherine is in the north of the capital today to open a new art room at Northolt school. And she's giving a lesson in thrifty style once more by swapping the designer gown we saw earlier in the week for a cobalt blue knee-length frock from LK Bennett
. The £225 frock is yet to sell out so why not add this investment piece to your wardrobe now?
