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