This term refers to the neckline of a dress. It is often used to describe the plunching necklines of women's dresses in the early 19th century--namely a strapless dress or one with a plunging neckline. Children, both girls and young boys, in the early 19th century wore similarly styled dresses, althought not with the dfaring necklines of fashionable women of the time. HBC notes that some slightly older boys not yet ready for trousers might wear their dresses with blouses. See, for example, a 1838 German painting.
