Pippa Middleton becomes a guest at Sir David Frost’s annual summer party.
The sister of Duchess Kate interacts with people from the media, politics and showbusiness, including Sir Michael Caine, Stephen Fry, Sir Elton John and Sir Bruce Forsyth. She is wearing a red lace sleeveless dress with nude underlay and sheer top. She matches her dress with a £135 pair of suede strapped wedges by Ash. According to Sir Frost, Pippa is invited because he met her before the wedding and she has since been to dinner at his house in Chelsea so she is a friend.
