What’s the secret to looking like you’ve got one eye on next season? Take a tip from pro-in-the-field Alexa Chung and fresh-faced Hetti Bywater (aka Ian Beale’s daughter in EastEnders – we know, she’s grown upa lot right?) and fling on a cardigan or leather jacket over your summer-friendly yet ever-so-next-season denim dress (forget black, true blue and chambray denim are your tickets to A/W’13 cool).
