Well. While I've got a handful of J. Crew shirts filling some voids, I've got to recommend Gitman Vintage, though that probably comes as no surprise if you've been around the forums a little while. Gitman works best for broad shoulder types. I'm a short, stocky guy and a medium looks like it was poured over me. They are the very best fabrics in a classic, but slim cut. You'll be wearing them in 2020 and they won't look out of date. Our Legacy gets some love here too, as does WvG. Check those out. And Band of Outsiders if you are tall and slim (though $250+ for a shirt is a little out there for me, yet somehow I continue to justify my growing Gitman collection).
