FreshPolos.com was started by a guy in search of the perfect-fitting polo. He always had trouble figuring out his size in the different brands—especially online. Like most entrepreneurs, he decided that if he couldn’t find it, he’d create it. The result is the TRUfit Guide.

The TRUfit Guide takes the guesswork out of choosing the right size by visually demonstrating how each brand of polo shirt will look. The guide shows photos of four guys who are each modeling a different size of the same shirt. Each model’s height and weight is noted, so you can compare your own measurements to gauge how that particular brand polo will fit you.
