A lingerie underdress is a type of undergarment worn by women that is designed to be worn under clothing to provide a smooth and seamless appearance. It is typically made from a lightweight, stretchy fabric, such as nylon or spandex, and may have cups or padding to provide support for the breasts. The underdress may also have straps that can be adjusted for a perfect fit and to ensure it does not show under clothing.
Lingerie underdresses come in a variety of styles, such as camisoles, slip dresses, babydolls, and bodysuits, and can be worn under a variety of different garments, including dresses, skirts, and pants. They are often worn to smooth out any bulges, and to create a sleek and polished look. They may be worn as regular undergarments or as a fashion statement. It can also be used as a lingerie itself.
