Bloomers= Though originally an outergarment, it later referred to an undergarment worn by women made of silk, cotton or wool, fitting tightly at the knee and waist.
Braies= Scottish men wore these under their kilts, much like a bloomer made of linen or wool, braies fit loosely and reached to the mid-calf.
So while visible bloomer line was not that exciting, visible whale bone line was enough to make a man blush for a week. Corset edges were also a lucky experience for anyone who could catch a glimpse.
