Gabriela Hearst - Gabriela Hearst takes inspiration from 19th century photos of working women for her AW18 collection, of which this camel-brown virgin-wool blend Armonia Burns trench coat is a key piece, first spotted on the runway. It's shaped for a slim fit with a purple wool-blend check double-bodice that features classic shoulder epaulettes and a coordinating waist tie, then falls into a panelled skirt, lined with satin. Wear it with the corresponding trousers and white heels for a considered daytime edit.
