COS Relaxed Poplin Shirt
About COS’s button-ups: Architectural poplin, oxford, and linen shirts in both relaxed and tailored cuts.
Is the price honest?
Mid-tier pricing for good cotton and a strong design point of view. The value is in restrained styling and proportion as much as the cloth itself.
Our take
COS approaches the button-up with a minimalist, architectural sensibility, offering crisp poplin, oxford, and linen shirts in clean solids and considered cuts. The styling balances modern relaxed silhouettes with sharper tailored options.

- Quality

- Best for
- Minimalist, design-forward wardrobes, worn relaxed over trousers or tucked for a sharper, modern line.
- Care
- Machine wash cold; iron poplin for crispness and let linen wear with a relaxed, natural crease.
