Sea Island Cotton
Designating a fine variety of cotton, Gossypium Barbadense, distinguished by long silky fibres.
Originally grown on islands off the coast of Georgia and South Carolina, Sea Island cotton was rushed to Jermyn Street for the making of Gentlemen's fine shirts and heliotrope striped pyjamas.
It has come to The Chaps' attention that some upstart clothing companies are claiming to use Sea Island cotton for something called ready-made.
Sea Island Cotton shirts come from Jermyn Street.
Anything else, from anywhere else, is just a bloody shirt.
