Are you sure that they are made by Isaia? I know they are made with Loro Piana cloth, but I am not sure about the maker. I just picked up a navy blue one in Super 160s. It is a lovely suit, IMO, but we will see how it holds up.
I realize that. FWIW, the DCS I bought has lovely pick stitching, is luxuriously soft and lustrous, and is pretty great all the way around. I think, more than anything, time will tell if this was a good buy or not. I got it for 50% off retail, BTW.
How can you know if the suit is really an Isaia? I just bought one of the Daniel Cremieux Signature suits for $104 at a Dillard's Clearance center. It is a 160's and says made in Italy. It's with the tailor now.
Most of the standard stuff is Canadian. Bought a number of SC's and the quality is a bit all over. RN numbers say jack victor for most "non-signature" items. The fabric tends to be pretty reasonable especially if you get the ones made with Loro Piana. Dillard's 50% off sale prices typically allow you to get the SCs for about $100 and the suits for $300 (or less).
