With a relaxed cut and curved hem, the Osvald shirt from Norse Projects is a fantastic option for a casual outfit that still calls for a collar. Thanks to the fabric choice on this version, the laid-back character of this style is teased-out even more.

A garment-dyed cotton twill gives a workwear edge with worn-in feel thanks to the washing process that gives the fabric its colour. Contrasting against the sheen of Mother Of Pearl buttons, this sturdy-yet-soft fabric makes this the sort of shirt that gets better with age.
