The fairy-tale theme of the ball (Alex de Betak has constructed a set in Valentino’s garden its owner describes as “huuuge”) is not just an excuse for fashion escapism. It underlines Vodianova’s campaigning determination to improve the life chances of underprivileged and handicapped children in her home country, a responsibility fired by her own background, and the struggles of her sister, Oksana, 22, who has cerebral palsy. “We already have 60 playgrounds built—but we want 500. So far, the Love Balls have raised over 10 million euros. So,” she said with a smile, “we need quite a little bit more.” The red Valentino dress, an exceptional one-off piece, will be sold, of course, right off Vodianova’s back tonight. White Fairy Tale Love Ball–goers, please take note.
