It was a jubilant affair in Althorp, Northampshire as Ralph Lauren celebrated its continued partnership with The Royal Marsden, a cancer treatment hospital in London, as well as the 15th anniversary of Pink Pony, the brand’s own effort to help combat cancer. Lords, ladies and stars such as international model Caroline Winberg and Entourage actor Jeremy Piven came decked in their most glamorous ensembles for the evening, and were treated to an exclusive fashion show and dinner.
