A backless dress is a style of women's clothing designed to expose the wearer's back.
[2] In December 1937, the actress Micheline Patton was controversially filmed from behind while wearing a backless dress in the final episode of the early BBC fashion documentary Clothes-Line.
The most common is by a single piece of cloth or strap which passes behind the wearer's neck, halterneck-style.
[4] The neck strap can itself be covered by the wearer's hair, leaving the impression from behind that nothing is holding the dress up.
[5] The backless style is also found in the choli, the blouse worn by Indian women along with saris and ghagras.
