The soft simple one color garment is the most basic form of a dress. It's like a T-shirt. There are a million ways to make it look new and different each season.
Directly descended from the plain, one-piece —silk, satin, cotton, or a synthetic—worn as undergarments from the 1920s through the 1960s, these dresses became, in the 1990s, the very definition of easy, sexy cool outside the boudoir.
