In the late 1920s and the 1930s, many evening dresses had low-cut backs, revealing a so-called back décolletage. The design of this brassiere accommodates this style: the straps can be wound around the body, leaving the back bare. The model is called ‘Le Grisina Invisible’ (The Invisible Grisina), because the flesh-coloured tulle was practically invisible when the bra was worn.
