London-based motorcycle collective BOLT collaborates with Edie Ashley, a pattern-cutting graduate, to create these moto-inspired black trousers. Made in the UK, they’re crafted from surplus cotton satin that would otherwise have gone to waste to a high-rise, slim-leg shape with sporty white side stripes and diamond-quilted knees. Style them with a T-shirt and the matching jacket, then fasten the silver zips at the cuffs.
