The bed jacket, a woman's garment, is a waist-length robe worn to cover the chest, shoulders and arms while sitting up in bed. Its short length and cape-like cut allowed it to be put on (or removed) while in bed. Often made of sheer or lacy fabrics and displaying very feminine trimmings and details, it was often used more for seduction, rather than warmth or modesty. It was popularized in 1930s Hollywood films featuring glamorous settings and glamorous stars lounging languorously in their silken bedrooms. Ostrich feather tips, swan’s down, pleated tulle and shirred lace were just a few examples of the extravagant materials that could be used in creating these confections. These garments are currently very popular with people who have been hospitalized or recommended bed rest.
Sometimes, they were akin more to a cape in style, for something to throw over your shoulders easily.
While bed jackets appear to be a thing of the past, I think it's shame. You can just throw something pretty over your shoulders while reading in bed. Seems like a good idea to me. Must get knitting.....
