"String vests" typically refer to a type of lightweight, open-knit vest or undershirt made from a mesh-like fabric. They are also known as "string undershirts" or "mesh vests." These vests are characterized by their distinctive pattern of large, diamond-shaped holes created by a loosely woven fabric. String vests are often worn as an undergarment to provide some insulation and can be particularly comfortable in warm weather due to their breathability.
These vests were historically popular in the United Kingdom, especially in the early 20th century. They were considered practical for regulating body temperature and providing comfort. However, their popularity has waned over the years, and they are less commonly worn today, with modern materials and clothing designs offering alternative options for underwear and undershirts.
