We know that this frock was in use during the 18th century and right through to the mid 19th century as a plain frock made from either a coarse linen, hemp, or wool. I have said in the past that I believed this frock to date back to the medieval period, though it may have been called by another name. Recently whilst researching something else (isn't it always the way!), I came across a 16th century painting showing a man in a butcher's shop wearing this same shirt style work frock.
Butcher's Shop by Annibale Carracci, 1580.
Detail from above painting.
