Shirt Loops
These loops can be found on shirts and some nice collared shirts. Apparently, the Navy started this practice because there is limited closet space out at sea and they had to hang their shirts on hooks. In the 1960s, college students hung their shirts during gym class to keep them neat and wrinkle-free. These days, loops are added because they symbolize class and quality.

Gas Gauge Arrow
Those who drive cars have probably noticed the arrow next to the fuel gauge since most cars manufactured starting in 2010 until now have this. This arrow reminds the driver whether the fuel cap is on the left or right side of the car. This is pretty useful if the car is brand-new or if it is a rental.
