The John W. Nordstrom tailored fit isn't bad ($89). Nordstrom also has a cheaper house brand if $89 is too much, but the fabric isn't is nice. With regard to Odoreater's BB suggestion, they're having a sale on the website for 3 for $189. You might also want to check out the clearance/overstock sections for Lands End, Jos. A Bank and Paul Fredrick. Not necessarily the greatest shirts, but a decent value on sale and they all have pretty good return policies. If your looking to build you wardrobe fast, they could be good options. If you want try the Tyrwhitt shirts, click the link below, it will provide a 50% discount rather than the 25% you'll get if you go to the website directly. http://www.ctshirts.co.uk/pine
For pants, you might want to try Incotex. There are some fantastic deals from Chorse at this thread if he has anything left in your size. http://www.styleforum.net/showthread.php?t=21731
And, Lance at www.virtualclotheshorse.com
just got a lot of new Incotex pants in. In any event, when looking for pants that have a slim fit, think flat front.
