What is a pinstripe?

A pinstripe is a narrow, vertical stripe commonly found on fabric, particularly in suits and dress shirts. It typically consists of fine lines that can be subtle or more pronounced, often created through weaving or printing on the fabric. Pinstripes are associated with formal attire and are often used in business settings, conveying a sense of professionalism and sophistication. The pattern has historical roots in menswear, particularly in British tailoring.
