Not that I would ever have such a use for this service, yet I still find it awesome. You can completely custom-make your very own Brooks Brothers dress shirt here. Brooks Brothers clothing is classic, conservative, and a definition of American style. Whether dressy or casual, you'll find it online at the Brooks Brothers store.
God, that sounds like a commercial. But, I really like their clothes. I'm thinking a navy blazer/sport coat when I get home. Something nice so I can dress up some khakis and a dress shirt. You know, in case I need to go somewhere that requires a jacket, but I don't want to wear a suit. That'll do it.
