pin-striped

The term "pin-striped" is a modern English compound adjective. Its first element, "pin," originally denoting a small, thin fastener, is used metaphorically to indicate extreme thinness, akin to the width of a pin. The second element, "striped," directly describes the presence of lines or bands. The compound emerged in the late 19th or early 20th century within the context of tailoring and fabric design, specifically to describe a classic, fine-patterned suiting material. The logic is transparent: it literally means "striped with pin-thin lines," a description that perfectly captures the visual characteristic of the fabric.

Structure: pin (pin) + striped (striped) - pin: From Old English pinn (peg, pin), of Germanic origin. In this compound, it functions as an intensifier meaning "very thin or fine." - striped: From Middle English, derived from the noun stripe (a line or band). It functions as the core adjective, describing the pattern.
