Yves Saint Laurent Kouros — Type Formula
The legendary powerhouse of animalic civet, honeyed florals and clean aldehydes.
A bold 1980s statement, it fuses fresh aldehydes and bergamot with a honeyed carnation-jasmine heart. Civet, musk, leather and moss create its infamous clean-yet-animalic signature.
