Not a Tux, but I need a suit
Along the same lines as Sidewinder: Many years ago, I did business with a Korean tailor and cobbler who were top notch: quality cloth and style for both the suits and the shoes. And the haircuts were also pretty sportin’. I don’t know how good Korean tailors and cobblers are today, but I hear – since the 1988 Olympics – you no longer get a “fluff girl” with the haircut. The tailors in Taiwan also have an excellent reputation for making outstanding suits, but I do not know that from personal experience. Sidewinder's recommendation is certainly the most tempting.
I was going to say Norstrom Rack or any high end department store outlet...just make sure the suit is still in style. No 4-button suits!
