BB or Nordstrom probably.
Joseph A Bank has the tailored fit shirts that I love, but freaking everyone shops there and I see the same shirts I bought there everywhere.
Jos A. Banks is a good store if you hit the right sale. Last year I bought 3 suits, 3 shirts, and four ties for around $1k (after paying for alterations and a permanent crease). The deal was "buy one suit, get two suits free, plus 3 shirts." The ties were buy one get one free. The highest priced suit was about $800. I'm very happy so far with the quality. Plus now that I've shopped there once and joined their buyers program, I get frequent discount coupons in the mail ($25 off any purchase over $50 usually).
If I were just buying a single sport coat I'd probably look at Mens Warehouse.
