Our knitted Riviera shirt is made from100% organic cotton from the great Trifitrofa Mill in Portugal. The dark navy cotton has a fine gauge with a supersoft handle and is fully fashioned with a dropped shoulder seam to create a clean profile. The fine jersey knit has re-enforced double ribbed base and cuffs, tipped with a contrasting white stripe. For the navy tipped collar and fine striped placket we've chosen a Milano stitch – a dense, flat, double knit with great strength and stability.
