A nighty, also known as a nightgown or nightdress, is a loose-fitting garment worn by women for sleeping or lounging. It is typically made of soft, comfortable fabrics such as cotton, satin, or silk. Nighties come in various styles, lengths, and designs, ranging from modest and traditional to more revealing and sensual. They can feature different necklines, sleeve lengths, and decorative elements such as lace, ribbons, or embroidery. Nighties are designed to provide comfort, freedom of movement, and breathability during sleep. They offer a relaxed and feminine alternative to pajamas or other sleepwear options.
