A backless ress is a dress designed so as to expose the wearer's back and. It is usually the equivalent of a floor-length haltertop, with a single piece of cloth passing behind the wearer's neck to hold the dress up, which may be covered by the wearer's hair, leaving the impression from behind that nothing is holding the dress up. In some designs, the dress includes short sleeves which hold the dress up by the shoulders, while still others may use spaghetti straps which connect to the sides of the dress.
