Pin striping
Pin striping describes the application of a pin stripe: a very thin line of paint or other material, generally used for decoration.
In automotive body work, pin stripes can either be a thin vinyl tape or paint. The tape versions are adhered directly to the painted surface in the pattern desired, while painted ones are done by skilled artists with specialized brushes. The goal of pin striping is to enhance the contours of the surface, and the lines are generally of a complimentary color. In any other form of decorative pin stripes, the goal is the same.
It can also describe a pattern of very thin stripes running in parallel found in cloth. Although mostly found in men's suits, any type of clothing can be pin striped. The New York Yankees baseball team's uniforms have had pin stripes for nearly 100 years.
