petticoat

A petticoat is a women's undergarment worn under a skirt or dress to provide fullness, shape, warmth, and modesty. It is typically a separate garment that fastens at the waist and falls to a length that can range from above the knee to the ankle. Petticoats may be worn alone to adjust the silhouette or layered to achieve more volume for the outer garment.

Construction and materials vary widely. Traditional petticoats are often made from cotton or linen, with newer versions using satin, silk, or synthetic fabrics. They can be unlined or lined for warmth and opacity, and may feature decorative elements such as lace trims, ruffles, or embroidery. Modern petticoats frequently have an elasticized waist for ease of wear and are designed to be washable and comfortable for everyday use, as well as for costumes.

History and use have evolved over time. Petticoats date back to early modern Europe, where layers of skirts and undergarments were employed to create fashionable silhouettes. In the 18th and 19th centuries, multiple layers of petticoats contributed to the voluminous skirts associated with certain styles, sometimes in combination with hoops or crinolines. By the mid-20th century, everyday use declined in many regions, but petticoats remained common in vintage fashion, theater, and ceremonial attire. Today they are still used as slips or decorative underskirts and continue to be produced in lightweight materials for modern wardrobes and costume contexts.
