"Underpinnings" refer to all the
underwear and support garments that help to keep clothing clean (protection from sweat, body oil, etc.), supportive (bras,
corsets), and correctly shaped (hoopskirts, petticoats). As fashions changed through history, the undergarments were
also redesigned and reshaped. It often took many layers (for both men and women) to get the final appearance of a well-dress
member of society.
