Bedgown

A bedgown (sometimes bed gown, bedjacket or shortgown) is an article of women's clothing for the upper body, usually thigh-length and wrapping or tying in front.

Bedgowns of lightweight printed cotton fabric were fashionable at-home morning wear in the 18th century.

Over time, bedgowns (also called in this context shortgowns) became the staple upper garment of British and American female working-class street wear from the 18th to early 19th centuries, worn over petticoats and often topped with an apron.

[1] The term "bed gown" to describe this item of clothing was used as late as 1876.

[3] Bedgowns lingered as fashion garments into the mid-20th century, usually under the newer name bedjackets, in the form of short robes or wrappers worn over a nightgown or negligee for warmth and modesty while sitting up in bed for breakfast, reading, or similar pursuits.
