Saint Laurent long lavallière halterneck dress

This black Saint Laurent lavallière halterneck dress is crafted in Italy from a black and silver tone silk blend and features an all-over metallic leaf print, a halterneck with a back neck tie fastening, an open back and a mid-length hem. Reminiscent of Saint Laurent's '80s collection that paid homage to Shakespeare, this dress glitters but is not gold. Now, when to wear it? That is the question.
