When it came to buy a jacket I too went with a tailor made one. I Checked out Langlitz when I was in Oregon and liked their stuff. However in the end I went with Bates Leather because they are close to where I live. My Bates Jacket and Chaps are 15 years old, and still fit. They did get a tad tight, but a little work on my part took care of that.
I have looked at a ton of off the rack stuff, but in the end, for me nothing fits like tailor made. Yes it is expensive, no doubt about that. But when I bought it I was looking at a long term purchase. Something to keep forever. In the time I have had my leathers, I have had ridden five different bikes.
For tailor made, I put Langlitz, and Bates, in the same boat. Good quality stuff that will last a lifetime. FoxCreek runs a close second. I'm sure there are other quality Made in the USA leatherworkers out there, but I can only speak for what I have worn.
