If your penchant for retro 50s style is more tailoring-centric than full skirts and petticoats, you may wish to take a gander at this Fanfare jacket from J Crew.
Inspired by the eponymous Chanel suit beloved of the likes of Jackie O and Coco Chanel herself, the cosy wool jacket is cut in the classic cropped, boxy style. The use of the monochrome colour scheme is contrasted with the rather fancy gold toned buttons typify Francophile 50s chic. Pair with a pencil skirt and enormous sunglasses to complete the look.
The Fanfare jacket is £280 from Net-a-Porter.
