Maybe it's the latest travelling exhibiton from the house of Chanel that has re-ignited the spark for this timeless trend on next spring/summer's catwalks. Or maybe it's just a collective style zeitgeist from international designers that has propelled this fashion classic into the spotlight, although whatever the reason, next season the core fashion piece to own is a two piece suit comprising of jacket and matching skirt. Also known as the 'Costume' their popularity on the spring catwalks is possibly due to the fact that the Chanel exhibition 'The Little Black Jacket' has been touring worldwide major cities since the beginning of the summer. The exhibition which is currently in London, will move this autumn on to other european cities, including Paris and Berlin. It has already been presented in New York, Tokyo and other influential asian cities. It is a rather simply presented show, with superb photography and styling under the direction of Karl Lagerfeld and Carine Roitfeld respectively. Narrative and text are minimal as the show focuses on the images of the simple black Chanel jacket and how it can be re-styled and worn in many various guises on diverse high profile fashion and celebrity figures. There is, although, a somewhat poignant statement at the start of the show ' There are clothes which keep rejuventaing themselves instead of getting worn out' a quote from poet Roberto Juarroz. And the boring old much bandied-around saying and non poetical cliche of 'tough economic times' sums up perhaps why it proves to be a catwalk trend for next season. Go see the exhibtion or buy the accompanying coffee table tome for ideas on alternative styling of this timeless classic. Or, see how other designers such as Balenciaga, Helmut Lang and of course, Chanel are declaring it's reinvention for Spring/Summer 2013.
