Look for a loose, dress-like cut (for example a relaxed v-neck slip) and styling notes that suggest pairing with a hat, belt, blazer, or coat. These design cues let some silk-style nightgowns double as simple daywear.
Most listings use polyester or polyester blends rather than true silk. Examples include 100% polyester and blends such as 95% polyester/5% spandex; some items list spandex as a component for stretch.
Care typically recommends gentle or cold machine wash and hang/air dry. Additional notes often advise washing on low heat, avoiding bleach, and one listing mentions tumble-dry-low.
Styles include sleeveless pull-on chemises, short-sleeve pull-on styles, and long-sleeve button-down nightshirts. Closure types are mainly pullover and front button-down.
Both formats appear: some listings are sold as 2-pack sets while others are single nightgowns.
