Our Tenue. Ralph shirt is a modern take on true Ivy style: the button-down shirt. The perfect shirt for both casual and formal occasions. Ralph features a regular fit, a single chest pocket and mother of pearl buttons. The Tenue. Ralph Ithaca wash is inspired by a vintage denim shirt from the Tenue. denim archive. The shirt is made from a 100% cotton denim fabric, of which 20% is recycled. This ensures supreme quality while reducing the shirt’s footprint. This Ralph shirt is made in our denim factory near Umbertide, Italy.
