Cotton comes from the family Gossypium, and the species hirsutum is the most common. If a garment is labeled "100% cotton", you usually get hirsutum. This species accounts for approximately 90% of the world's production.
Dress shirts in 100% cotton
The finest cotton comes from the species barbadense (only about 8% of world production), which gives extra long fibers which, in turn, can be spun into finer yarns and woven into fantastic fabrics.
You probably recognize barbadense cotton by its more common names, Egyptian (Giza) cotton, Pima cotton (grown in North and South America), Sea Island (grown in the Caribbean), and a few others.
Egyptian cotton, or Giza cotton, is the best-known Barbadian cotton. It is known for its long fibers (around 30mm+) and is woven into extraordinarily soft and wrinkle-resistant shirt fabrics.
Premium dress shirts in Egyptian Cotton
Our fabric family Savile Row is woven from Pima cotton and is really affordable. Pima grows in North and South America and is not quite as well known as its Egyptian cousin. It has similar fiber lengths and fine properties, making it suitable for shirt fabrics.
Sea Island is the king of cotton. It is an absolute luxury with its extreme fiber lengths (50-60mm). This amazing cotton is only grown around Barbados in the Caribbean, with minimal production. Unfortunately, this makes Sea Island cotton fabrics incredibly expensive and exclusive.
