You can't go wrong with a bit of seersucker in the summertime. This shirt from Corridor's rocking a particularly nice super-soft version that pairs cotton with a touch of viscose which brings both softness and a liquid feel. The cloth gets a nice bit of structure thanks to the intermittent stipe running across the recognisable bubbled texture.
OMTC in Madras, India makes these for Corridor using a combination of modern technology and age-old techniques which have existed on the continent for generations.
