Complete with long sleeves, thigh-skimming length, ribbed fabric, and collar poking out, this Carven dress is a preppy-chic endorser's dream. So it's hardly surprising to us that both Alexa Chung and Emma Watson chose to add it to their indie-cool wardrobes.

While Alexa went for the black version, pairing it with a little Chanel bag and mary-janes, Emma opted for cream, and her matching peep-toes upped the glam factor as she chatted about Harry Potter and the Deathly Hallows part one.

Despite Emma braving some sky-high heels for the look, we're voting for Alexa in this round. But who do you think wore Carven best?
