A Storied Past

Sea Island Cotton dates back to the 18th century when it was cultivated on the barrier islands of South Carolina and Georgia before flourishing in the Caribbean. Because of its rarity, it quickly became the preferred cotton for European luxury houses, worn by royalty and aristocrats who valued its unmatched softness and breathability. Today, Sea Island Cotton remains one of the most exclusive cottons in the world, with only a limited quantity produced each year—further enhancing its desirability.

A Commitment to Quality

Harvesting Sea Island Cotton is an exercise in patience and precision. Unlike conventional cotton, which is typically harvested mechanically, this rare fibre is picked by hand—a traditional and respectful method that ensures the highest quality. Handpicking allows for greater control over the harvesting process, resulting in cotton with minimal impurities. Once harvested, the cotton is carefully packed in air-permeable bags or sacks to preserve its pristine condition.

Every kilo of locally produced Sea Island Cotton is inspected and certified by the West Indian Sea Island Cotton Association (WISICA). Each piece made from this rare fibre comes with an original certificate of authenticity, complete with a special hologram as a guarantee of its provenance. This meticulous process ensures that only the finest fibres make their way into garments around the world.
