Satin-Trimmed Backless Velvet Waistcoat

Anthony Vaccarello channels Yves Saint Laurent’s fabled 1966 Le Smoking suit with this evening-inspired waistcoat — the ensemble was famously worn by French singer Françoise Hardy during an evening at the Paris Opera in 1966. Italian crafted from light-absorbing velvet that’s trimmed in satin, the halterneck plunges into a deep V, while the open back adjusts with a buckle. Style it as the high-octane finish to sharp tailoring.

• 100% cotton. Lining: 100% silk
