Maria Sharapova, Stella McCartney and Camilla Belle

The launch of the Stella McCartney Organic Collection saw a swathe of glamorous guests RSVP 'yes' to an invitation to dinner at Harvey Nichols in London. Among them were Maria Sharapova, who had evidently put her recent defeat at Wimbledon behind her as she wafted around in a white chiffon cocktail dress, while starlet Camilla Belle opted for a dress in royal blue satin. Masses of pink peonies, the season's chicest flower, scented the dining room, with each of the lucky guests receiving a bespoke napkin ring embossed with their name - a fitting souvenir to celebrate Stella's capsule range of organic and ethically produced clothes. -Danielle Radojcin
