I was never that keen on the Papillion gear. Last few I bought from these guys - highly recommended (from me at least) http://www.thecordialchurchman.com/
r.e. singlet - wear a three piece, problem solved!
I contacted thecordialchurchman.com but they never got back to me, it also just so happened that Le Noeud Papillion had 40% off the bow tie I was after..
I really don't like 3 piece tuxedos
