Geeks are having a moment. Shirts buttoned to the top, playsuits with collars, satchel bags and geek glasses are a slick way to see out the last of summer and the coming autumn season. It’s a great look for the office and also very hip when clashed with ripped jeans, leather shorts or trainers. So do as J Crew, Carven and Victoria Beckham did and keep it preppy. It’s a little bit geek chic and a whole lot of cool.
