Corsets are a type of clothing that is designed to shape and support the body. They are typically made from stiff fabric and have lacing or other fastenings at the back. The term 'corsets' comes from the French word for 'stays, ' which is the type of boning used in the garment. Stays are pieces of material, usually whalebone or steel, that are inserted into the fabric to provide structure and support. Corsets have been worn since the 16th century and were popular during the Victorian era.
