A summer staple, the right pair of sunnies will take you from a picnic in a city park to olive groves in Puglia. From neubau's plant-based frames to Gentle Monster's Willy Wonka-eqsue shapes and easy-on-the-eye (and wallet) Izipizi, these are the shades we're slipping on this season. The best thing we've discovered this year? Tortoise + Black's nifty delivery service - pick four pairs from their curated selection of designers from Tom Ford to Chloe, try them on at home, then send back the ones that aren't for you. With a prescription service also available, it couldn't be easier.
