What does nightdress mean?
A nightdress is a light, loose garment worn in bed, for sleeping, or sometimes for relaxing at home. Unlike a formal evening dress, it is designed primarily for comfort and is commonly made from cotton, silk, satin, or similarly soft fabrics. Its appearance can range from simple and practical to decorative and traditionally feminine, with details such as lace, embroidery, or ribbon trim. In everyday use, “nightdress” is closely related to “nightgown,” although “nightgown” may suggest a more decorative style. The word is familiar in British and American English and is especially associated with a traditional image of getting ready for bed or relaxing privately at home.
