Superb sweet floral musk and very strong and long-lasting as well.
This formula is the base for three other classics:
Rochas' MADAME ROCHAS
Oscar de la Renta's POUR LUI
I recommend the first two to men as well, since I find them unisex in their appeal, although originally formulated as women's perfumes. [Heck, men love chypres and these were all originally designed for women.]
