I happened to find the first suit I ever owned: a 1987 Nordstrom charcoal gray pinstripe suit. Other than two very small holes near the collar (moths?) and a few inches of the liner near the arm hole needing to be sewn it is in perfect condition. And it fits perfectly! I don't know the thread count of the wool but I can say this: it is thick. Whether we're talking cotton, wool, poly, or anything else, clothes made over the last 10 years or so are thin, essentially a way of giving consumers less for a given price. My Nordstrom suit is really substantial -- you can both see and feel the weight of this suit. I was stunned when comparing it to other suits I have. And, to quote the label inside the jacket: "Made in USA with imported wool".
