Fashionably blue! Is it possible for one woman to have this many perfect outfits? Well apparently not. For the hundredth time, we find ourselves coveting Jessica Alba's casual but chic style. This week she taught us all a lesson on double denim. It's a look that has been widely criticised, however, if executed right...it could become one of your go to outfits. This look is best worn with heels to feminise and smarten the whole outfit. We'd also opt for boyfriend cut jeans over your everyday skinnies. If double denim is a bit daring for your liking, then trade in the denim shirt for a blue cotton one (we happen to adore this one by Liberty).
