Celebrities wearing designer anything isn't news. But, what isn't expected are the labels these leading ladies are flocking toward for spring. Lately, it seems, it's all about the Brits. Sharing the red carpet with established Parisian, American, and Milanese houses are relative newbies like Paper London and House of Holland and trendy London-based labels like Mary Katrantzou, Giles, and Christopher Kane. It's what we're deeming Hollywood's latest wave of Anglomania.
In recent seasons, as London Fashion Week has grown exponentially in popularity, so have the event's participants. Once-indie Brit brands have now achieved legitimate cult status — Peter Pilotto's Target collection is evidence of this fundamental fashion shift. And, today's A-listers are living, breathing proof as well. Leslie Mann, January Jones, Emma Watson, and up-and-comer Margot Robbie are just a few stylish celebs sourcing inspiration from across the pond. Click ahead to get a peek at the designers these ladies are loving right now, and (window) shop 'em too — that is, if you have an event that warrants red-carpet-worthy style.
