The term 'Tight Undergarment' can be summarized as a garment that is worn close to the body and is usually used to shape or support the body. One example of this type of garment is a CORSET, which is a 6-letter word. Corsets are typically made of a strong fabric and are designed to be laced or fastened tightly around the waist and torso. They are often used to create an hourglass figure and are popular in fashion and costume design.
