Japanese label Factotum is known for its premium menswear and its shirts are no different. Its collections rooted in denim, the label fuses this focus with military and workwear references. The result is a luxe take on casualwear and off-duty dressing. Focused on simple and classic silhouettes, its men’s shirts are closet staples. Pared-down designs are made from denim and cotton and done out with contrasting details, prints and subtle finishes.
