An old undergarment is an item of clothing that has been around for a long time. Two examples of old undergarments are corsets and tunics. A CORSET is a tight-fitting garment that is usually worn to shape the body and provide support. It typically has laces or hooks and eyes at the back or front. A TUNIC is a loose-fitting garment that is usually worn over other clothing. It can be short or long and is often made of lightweight fabric.
