Gents, until recently I only had one truly heavy worsted suit. I don't even know the weight, as I got it as a close-out and the weight was not marked. it must be at least 14 ounces. That suit has always worn very well, but I never though about why much. Among the stuff that I ordered knowing full well the weight, I had never gone over 13 ounces. Until recently.
Earlier this year I ordered a Smith Woolens 15 ounce twill. You'd think that two measly ounces could not make a difference. Oh, but they do. As wonderful as Lesser 13 is, this cloth really hangs like steel. I have never seen trousers that hang so well, or crease so sharply. Or sleeves that fall so smoothly. I love the way the cloth feels when worn. It's heavy, yes, but not uncomfortable. It just falls into place. It really gives gravity something to work with.
