Signature Perfume by St Dupont, S.T. Dupont introduced Signature perfume, a floral, woody blend, in 2000. Top notes of tulip, bergamot and nutmeg capture your attention at the opening of the blend. Rose, iris and orchid amplify the scent’s sweetness and provide a pleasant powdery quality to the fragrance. Base notes of vanilla and Brazilian rosewood add depth to the blend. This lovely perfume is versatile enough to be worn both in the daytime and nighttime.
