It's going to be pretty tough, if my experience from 4 years ago is any indication. Scabal used to have a very limited selection, and that's what most English tailors will use. Teh RJmanbearpig has told me that Chipp/Paul Winston has his own very slubby tussah woven up, and sells lengths of it. Loro Piana might also have something, as might Byrne and Burge.
