Gingham is pretty proven as far as patterns go, but lots of guys usually reserve it for S/S - that probably has something to do with conjured images of picnic cloths. Personally, I think gingham works well in F/W as long as the color is right. By keeping the color dark you can add some visually appealing depth to your standard seasonal kit. Sticking with colors such as black, burgundy, and hunter green won't make you look like you're trying too hard and you'll stand out from the oxford and tattersall wearing crowd. Brooks Brothers has a bunch of F/W ginghams up now in their extra slim fit cotton broadcloth (single-needle tailoring) dress shirt style. I like BB's English collar and, while not as perfect as the cutaway, is a nice change of pace from all the button downs that probably dominate you closet. While this is a "dress shirt", I think it can be best utilized in more casual settings, with the collar and pattern combination adding a real punch to your F/W neutrals.
