Wool and silk cloqué gown with sheer V-necked panel and embellished cuffs, price unavailable, by Dior.
You already know the little black dress - the one-piece wonder that works from day to night. But what if the invitation says formal? Will even the most fantastical cocktail dress suffice? No. "Black-tie" is in a league of its own. So, look no further than a pouffy gown, which in classical black can be worn more than once. How you ensure this depends on how you accessorise, but of course.
