One summer evening, Jacques Guerlain was overcome with a feeling of deep turmoil. It was a time for rest; the time when the rays of sunlight disappeared from the sky but no stars could yet be seen. The whole world was bathed in a blue light. L’Heure Blue by Guerlain: this fragrance, this fragrance alone, is able to express this deep, heartfelt feeling. The curves that grace the top of the flacon represent the influence of art nouveau on this masterful fragrance.
