1. Loop On The Back Of Shirt
Most people look at the loop on the back of their shirt and wonder what it’s for. There is a purpose for it on the back of your shirt. There are actually three documented reasons and it’s unknown which is correct. The first is the most obvious, it’s a way to hang your shirt on a hook. This doesn’t make sense however because if you hang your shirt on a hook by that loop, it will become wrinkled quickly.
The second could be a way to help you fasten your tie easier. The last purpose is more romantic. Years ago, American University students were said to have removed the loop from the shirt when they started dating a girl exclusively to show that she was taken, the girl would wear a scarf with the University’s emblem.
