Before you can find a proper collared shirt, it might be best if you knew what kind of shirt to look for. This handy infographic shows nine types of common shirt collars. From the classic to the club collar, each shirt is designed for a specific look. Pick the right one and you’ll look sharp as a razor blade, but pick the wrong and you’ll just look silly, and maybe elicit some unwanted chuckles from your peers.

As always, study them, and be mindful of them when you’re shopping for shirts, whether that’s online or in stores. And don’t forget, how to match ties and shirts properly. That’s very important.
