Last night, a select handful of fashion mavens celebrated Rodarte designers Laura and Kate Mulleavy at a private dinner hosted by Kate Bosworth.

Guests including Emma Watson, Plum Sykes and Trish Goff joined in toasting the American design duo at London's luxury retailer Harvey Nichols, where Rodarte has been a smash hit.

Kate Bosworth looked radiant in a knee-length nude Rodarte dress with amazing back detail, while Emma Watson stunned in an edgy black and blue draped Rodarte frock. (Watson is clearly coming into her own -- her look would knock Harry Potter's cape off.)

The menu consisted of nettle soup, whole roasted lemon sole niçoise and strawberry three ways, while attendees toasted with signature drinks including a vodka, cucumber, mint cocktail, elderflower pressé and Harvey Nichols pink champagne.

A feast fit for an amazing design team!
