Isabel Marant - The refined cut of Isabel Marant's dark blue Niklas trousers reflects the brutalist architectural setting of the Parisian label's SS21 presentation. They're crafted from a Prince-of-Wales-check linen blend to a tapered silhouette that's punctuated with forward-facing pleats and turn-up cuffs - hallmarks of English tailoring. Wear them with a relaxed T-shirt to mirror the lookbook styling.
