Alexa Chung has been a huge style crush of ours since her T4 presenting days. Now with a successful fashion label of her own and star-studded entourage, she continues to deliver outfits that epitomise London It-girl cool. This weekend, she posted an Instagram picture that got us seriously excited about the season ahead. Wearing one of her own brand slogan tees, Alexa proceeded to drape a ribbed green jumper over her shoulders in a nonchalant fashion. The styling trick was so simple yet so chic. It's a preppy look that she has championed before, of course, with everything from tuxedo blazers to shirts to skirts (we're taking notes). It may be a simple styling move, but it's ideal for this time of year when the weather is starting to cool down. It's also a great way to show off your knitwear and allows you to go hands-free. Win-win. Scroll down to shop the look.
