This is always a big fancy fashion-y British party — it’s in aid of the Serpentine Galleries, which are awesome (every summer they have a groovy, temporary gallery designed by Someone Important, and I think this party marks that opening), and also it’s featured on at least one season of Ladies of London, so you know it’s legit. When there are fancy fashion-y British parties, so will there be models! Some of them…may regret last night’s choices.
