The Duchess of Cambridge Celebrate the Achievements of Sports Stars.

The Duchess of Cambridge, Patron of SportsAid, arriving for the 2013 SportsBall, the charity's annual gala dinner.

The Duchess of Cambridge joined Olympic athletes at a ball held to help the next generation of British sports stars. The Duchess was greeted by Olympic stars including Amy Williams and Dame Tanni Grey-Thompson at the Sports Aid event, for which she is a patron. She was also greeted by Anna Watkins, an Olympic gold medallist rower.

The Sportsball gala dinner is Sportsaid's major annual fundraiser. It also celebrates the achievements of the athletes the charity has supported over the years and looks to the future by shining a light on talent in the next generation. With this in mind, the Duchess will  present the One-to-Watch Award, which honours a young British sportsman or woman who has demonstrated extraordinary commitment to their sport and career and previous recipients include diver Tom Daley.

The Duchess wore a black dress designed by Alice Temperley to the SportsAid event, held in central London. She teamed the dress with Jimmy Choo shoes and a red Alexander McQueen handbag. The London Templeton dress, described as having an ‘Audrey Hepburn feel’, had been on sale for £398 but had sold out online on Thursday night, minutes after the Duchess appeared wearing it. The knee length dress had a crocheted skirt and three quarter length sleeves.

with an elegant off-the-peg Temperley dress accompanied by a pair of glamorous Jimmy Choos, she did just that.
