Everyone has that one shirt: a shirt so wonderful, you would happily buy a dozen more like it. Maybe–just maybe–a world like that will be possible someday soon, thanks to the Shirt Fit Finder. This site compares the sizing of different brands of shirts, and finding something similar for you to buy. The bad news? Their selection of brands and sizes is terribly limited. The worse news? It only works for men’s shirts. Ah, well. Someday.
