Girl With Tan Lines

• Taxi driver's arm
In the United Kingdom "trucker's tan" is known as "taxi driver's arm" and is exclusively, since driving on the left, the right arm which rests on the open window.
• Franciscan tan
A "Franciscan tan" is a tan that is associated to the Franciscan order. The reason behind this is that Franciscans usually wear sandals during the summer. This creates an odd tan line when the sandals are off because, depending on the sandal, the feet will have a tan line.
