About COS’s button-ups: Architectural poplin, oxford, and linen shirts in both relaxed and tailored cuts.

Price check

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.

The details

Material
Cotton poplin, oxford cloth, and breathable linen, with some structured organic-cotton blends for a clean, modern drape.
Fit
Ranges from relaxed and slightly oversized to a trimmer tailored cut; the relaxed styles have a fuller body and clean drop shoulder.
Quality
Clean seams, neat collars, and considered buttons give a polished, design-led finish. Construction is consistent and well above fast-fashion standards.
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.
