Kate Middleton, the Duchess of Cambridge, shops at consignment shops as well. But she did not buy the dress herself. She had her assistant go and pick up the dress. Kate wore the gray coat dress to the National Portrait Gallery a few weeks ago. The dress is vintage and was made my Jesire. The dress coat was purchased at The Stock Exchange near her childhood home. The store says that they were very excited that Kate wore the dress and they remember having it in stock. They are hoping that Kate Middleton sends her secret shopper there more often to find her some deals.
