I have zero experience with waistcoats or waistcoat materials. However, believe that within the last year there was a thread about waistcoasts revolving around one of the British horse race events. Epsom? At any rate, the waistcoat that Prince Charles was wearing was pictured; and there were a number of posts, mostly as I recall, where one could purchase one. Perhaps a search on the forum? Good luck!
