Tennis fan Pippa Middleton made an appearance at the Wimbledon tennis championships in London today, with her brother, master baker James.She was wearing a demure Orla Kiely number, making it hard to argue with royal arbiter @victoriaarbiter who remarks: "Sorry #PippaMiddleton fans but I thought today's #Wimbledon outfit made her look 105. Is she still repenting for the Paris gun debacle?"
