Shirt Loops
Shirts and nice collared shirts have these loops. Apparently, the Navy began this practice since they have limited space for clothing out at sea. These loops are used for hanging shirts on hooks. This is also true for college students back in the ‘60s. At the gym, they kept their shirts wrinkle-free and neat by using the loops to hang their shirts. These days, the loops signify quality and class.
Gas Gauge Arrow
The arrow next to the gas gauge is most likely familiar to people who drive cars. Just about every car which was manufactured from 2010 onwards has it. The arrow shows where the gas cap is found – on the car’s left or right side. If you drive a car that is brand-new or a rental, the arrow is pretty useful.
