Theater lovers, this one’s for you. From ushers to A-listers to those in the nosebleed section, Alber Elbaz covered every aspect of the showgoing experience with humor and panache. Should you fancy a black jacket or a white blouse, you’ll confront an embarrassment of riches. Same goes for a statement cocktail dresses (warning: short is in; alert your trainer accordingly) that will make your fellow revelers weep. But why not ditch the dress, at least just once, in favor of Elbaz’s double-breasted silk jacket, covered in periwinkle sequins and festooned with a ribbon or two? Piece by piece, there’s a lot to wear with more casual fare (which the Lanvin lady does brilliantly), but this season, especially, ditch the practical stuff, and go with the show.
