A corset is a close-fitting garment that is worn to shape and support the torso. It typically extends from the chest to the hips and is traditionally made of stiffened fabric or boning, which provides structure and helps to cinch in the waist. Corsets have been worn for centuries and were especially popular in the 16th to 19th centuries as a fashion statement and to create an hourglass figure. Today, corsets are still worn as fashion items, lingerie, and for waist training purposes.

Oversize, also known as oversized or oversized fit, refers to a style or fit of clothing that is intentionally larger or looser than the standard or traditional sizing. It is characterized by garments that have more generous proportions, with extra fabric and a relaxed silhouette. Oversized clothing is often associated with comfort, casual wear, and a more relaxed or laid-back aesthetic. This trend has become popular in recent years, with oversized shirts, sweaters, jackets, and trousers being commonly seen in fashion.
