Gabriela Hearst has only recently ventured into menswear, but she's already defined a relaxed way of wearing suits - take a tip from the designer's Instagram (@gabrielahearst) and dress down these 'Martin' trousers with the [matching jacket id1139434] and a T-shirt. They've been tailored in Italy from subtly checked wool with buttoned side adjusters and have unfinished hems, so you can customise according to your measurements.
