collaring

From: why collar size matters when it comes to men’s shirts.

“Get the collar size wrong and you may end up with an ill-fitting garment. In the best case, there will be a yawning gap between collar and neck and you will give the appearance of swimming in your shirt. Get it too tight and you start endangering your health as the carotid and jugular veins in your neck get restricted for 8 hours a day if you wear a tie for work.”

Eh voila! The puzzling world of the collar.
