A pinstripe fabric has a repeating pattern of thin parallel vertical lines.
This is an old pattern (references to pinstripes can be found in Chaucer's Canterbury Tales) and has been used for various different purposes through the years. Originally used mostly for formal trousers for London bankers (each bank had their own unique color and width of pinstripe fabric to denote their employees), it became a staple for American suiting during the 20th century (see Al Capone), and has remained tied to the finance industry. Beyond bankers and gangsters, for the most iconic use of pinstripes look no further than the New York Yankees home uniform.
Pinstripes have a slimming effect as the continuous unbroken lines visually lengthen your silhouette. Shop the collection here.
