Nightgowns and sleeping garments began appearing in written records and historical textile archives during the Middle Ages around the 15th century, though specialized loose garments worn strictly for sleeping evolved significantly during the Renaissance period. Before that era, people frequently slept naked or wore their daytime undergarments or shifts to bed. As textile manufacturing became more industrialized and domestic wealth increased during the Victorian era, nightgowns evolved into elaborate, decorative garments featuring lace, embroidery, and tailored silhouettes, eventually paving the way for modern sleepwear options.
