The name ‘L’heure Bleue’ means ‘the blue hour,’ and Guerlain’s L’Heure Bleue definitely evokes that hour before dawn and after dusk, where the sky is lit that iridescent, jewel-like blue. The scent is a very classic, feminine floral, and blends together notes of rose, iris and jasmine to create a bouquet for the skin. Best for casual wearing, the fragrance is recommended especially for springtime, and daytime wear.
