Jill Biden and Rishi Sunak Lunch Together in London.

First Lady Jill Biden wore a $15,900 designer dress by Gabriela Hearst to attend a lunch hosted by British Prime Minister Rishi Sunak and his wife at Downing Street in London. It is unclear whether the dress was purchased or loaned to her for the event. President Biden did not attend the lunch or the coronation of King Charles III, but congratulated the new king on social media.
