The "Buttoned Down" brand of men's dress shirts is fantastic. They have a huge range of colors and styles, and they take fitting very seriously. This is the only company I have ever found that understands the issues in fitting men's shirts, and they are the only dress shirts I buy now. Buttoned Down offers 100% cotton men's shirts in traditional collars and in the slightly casual buttoned-down collars, with many, many options. Every type of dress shirt comes in a selection of collar styles (point, spread, rounded, etc.), with options for chest pocket or not, and a variety of colors and patterns. The button-collar shirts have the same options (with the button collar, obviously). Every shirt comes in slim, average, and "tailored" (which is the loosest) body styles as well. Not every color or pattern is available on every shirt, but the range of styles is very broad. And most important, every single shirt can be ordered in a huge range of neck/sleeve combinations. Any combination of sizes from 14" necks to 21", with reasonable corresponding sleeves (and, again, three types of body fitting), is available. Now you can find the shirt that will fit you! If you have an extreme size (particularly the largest sizes), they've got you covered, unless you're really off the charts. This company knows how men should be fitted, and they give you the options to get almost anything you want. Also, the cotton fabric is really nice: heavy, finely-woven, and sleek. I'm a big guy, and I can't tell you what an amazing relief it was to find these shirts. (They have other types of clothing as well.) If you want heavily customized options at a very reasonable price, and particularly if you have trouble finding shirts that fit you, definitely check them out. I'll never go back!
