Earlier this week, Emma Watson stepped out in fashion brand of the moment – Carven. Emma wore a beige collar dress (£645), which you might recognise from Alexa Chung's recent Elle cover. Carven designer Guillaume Henry included this dress in his Autumn must haves. Alexa wore it in blue with flats, whilst Emma teamed hers with platform heels and a studded Burberry Spring '11 mac. Out of these two girls, which do you think wore it better?
