Girl With Tan Lines

• Driver's tan
A driver's tan is associated with extensive driving while hanging one arm out the window.
• Biker's tan
A biker's tan is tan line that goes up 3/4 of leg, where lycra bike shorts would normally begin to cover. Depending on the activity, the inner side of the arms may be paler than the outer side. Unless you use cycling gloves made to allow tanning, the area on the back of each hand will usually not be tanned.
