The term "Smock Frock" has various synonyms. In the past, it was known as a "tunic," which was an ankle-length garment worn by laborers in Europe. In some regions of England, it was also called a "frock coat," a "slop," or a "slop coat" due to its shapeless design. "Labourer's jacket" was another term used to describe the Smock Frock, which was worn by British farmers and traders. While "Smock" and "Frock" were the common terminologies used, other names that were occasionally used for this modest garment included "work jacket," "peasant blouse," "shift," and "over-shirt".
