With so many glamorous events leading up to the Queen's Diamond Jubilee and a bevy of award dinners and red-carpet galas, the UK may just have been the epicenter of chic this week.
In London, Natalia Vodianova hosted the NSPCC Pop Art Ball, where a gaggle of well-heeled guests — including Agyness Deyn and Naomi Watts — wore (what else?) ensembles by cohost Stella McCartney. Also in London, Glamour's Women of the Year Awards brought an array of good looks, with Lily Collins's strapless emerald Alexander McQueen looking especially enchanting.
Laura Bailey and Erin O'Connor (left) proved their model merit over in Epsom, England, at the Investec Derby Festival: both were equally stunning in their respective — and elaborate — bespoke fascinators made especially for the occasion. And in Oxford, Donatella Versace made her mark wearing glossy black Versace while giving a talk at the Oxford Student Union.
Those looks — plus more from elsewhere in the world, including Ashley and Mary-Kate Olsen in New York and Kate Moss in Barcelona — are here, in our best-of-the-week slideshow.
