I can only hope MrsKnB is joking when she posted the above sites. Unless you're under 25 with about 6% bodyfat, you'd look like a moron in any of the clothes on those sites. I.e. trying waaaaay too hard.
Try looking at ASK ANDY ABOUT CLOTHES or Style Forum - Discussion of Men's Clothing, Streetwear, Denim, Health, & Lifestyle . The former site is for older folks, the latter is for younger folks (hence, more BS to sift through).
