A slip dress is a woman's dress that closely resembles an underslip or petticoat.[1] It is traditionally cut on the bias, with spaghetti straps.[1] The slip dress looked like an undergarment, but was intended to be seen, and through the use of lace and sheer elements, offer glimpses of the body beneath.[2] Designers associated with slip dresses include John Galliano, whose debut design for Dior was a lace-trimmed slip dress worn by Diana, Princess of Wales in 1996;[3] Calvin Klein and Narciso Rodriguez.[1][4]
