Jos A. Bank is a store I frequent for work shirts. I like their Traveller's Collection of wrinkle free shirts. The shirts wear well and are good to take on cruise ships when you are not allowed to have a room iron. They also have nice ties which I have at least a dozen. When there is a sale; it's definitely work it to stock up. Our most recent visit in April 2012; there was a weekend sale. I bought one shirt; got two for free. Same went with the ties; which I purchased three.
They also carry casual shirts, outerwear, suits, tuxedos, socks and shoes. I've only bought shirts and ties here and I 'm not a fan of their suits.
