Dinner dress
From Infogalactic: the planetary knowledge core
A dinner dress is a gown that was worn by ladies in the Victorian era for dinners and parties at homes. It could be very elaborate, but often had long sleeves, a high neck, or a narrow skirt to set them apart from evening gowns. In the 20th century however, dinner dresses went out of fashion and were replaced by evening gowns for formal dinners.
