Kim was joined by Andy's mother Judy at the men's singles fourth round match. Judy had opted for a more low-key look and wore denim gilet over a grey jumper.
Kim is known for her love of reasonably priced clothes and is often spotted championing high street brands such as Whistles, Hobbs and Zara.
For the Wimbledon final that saw her boyfriend take home the trophy, however, she wore a £925 mint green Victoria Beckham dress.

At the time, Kim was travelling with her father , Nigel, who was head of the women's section of the Lawn Tennis Association in England.
