The latest addition to the Steven Birnbaum Collection  is “Fête,” the designer’s bespoke evening and cocktail wear label, which can be entirely personalized. The line, a diverse offering of garments perfect for so many of life’s biggest moments, can be summed up in one word: ageless. This is Steven’s exact vision for “Fête,” he says. After all, a single dress can and should look elegant and tasteful on any woman, whatever her age.
