Model Sophie Anderton opened a free open-air exhibition in support of Breakthrough Breast Cancer at the London Eye on Thursday night.
The former lingerie model arrived at the event in a daringly-cut black dress.
The exhibition, An Eye For Fashion, is a retrospective of the Fashion Targets Breast Cancer UK campaign and showcases the best photographs taken in support of the campaign since it began in the UK in 1996.
Models featured in the photographs – taken by world-famous photographers such as David Bailey, Mario Testino, Rankin and Ellen von Unwerth – include Yasmin Le Bon, Naomi Campbell, Jerry Hall, Jodie Kidd, Elle Macpherson, Kate Moss, Claudia Schiffer and Christy Turlington.
After the exhibition launch, celebrities including Emma Bunton, Caprice and Cold Feet star James Nesbitt attended a gala fashion evening across the river at the Savoy Hotel.
Stars were offered the chance to bid in an auction and raise money for the cause.
