Struggling to keep your smart/casual game together? Take our advice and channel some subtle European playboy vibes with loose, comfortable fabrics, like Ryan Gosling here. Think The Talented Mr Ripley meets James Bond making the most of a half-day holiday. 

Light colours, light fabrics and loose fits are the order of the day. Gosling's plumped for a linen-style shirt, a pair of Wayfarer-style sunglasses, some smart, slim, blue chinos and a pair of nicely weathered Derbies. Add a glass of something chilled and you're golden. Weekend, come at us.
