Unlike most aspects of military aviation, the ubiquitous bomber jackets remained largely the same since their introduction back in World War I. Still a favorite among today’s aviators, the practical nature of these functional outerwear have helped them to become one of the top fashion trends for Spring 2014. While classics like MA-1 have permeated throughout popular culture, here are the few other key designs we’ve picked out when they first debuted during last year’s fashion runways in Milan, Paris, London and New York. All of which are available now through MR PORTER online store.
