OFFICINE GÉNÉRALE Eren Camp-Collar Cotton and Lyocell-Blend Seersucker Shirt

Officine Générale's 'Eren' shirt is made from seersucker – a puckered fabric that'll keep you cool in warmer climes. It's woven from a blend of Lyocell and cotton, so it's at once soft and airy, and cut in a relaxed shape with a wide camp collar that lies flat against the chest.
