Givenchy did lovers of art history a huge service this year by reissuing its classic scents in an exquisite collection. The gleaming surface of L’Interdit (by the perfumer Francis Fabron) is the olfactory incarnation of gold. Jean Guichard and Olivier Gillotin have updated L’Interdit only slightly (all classics are refurbished to some degree when relaunched), softening the gilt of its rose and jasmine. But it is Givenchy’s Le De , from a 1957 formula by Ernest Shiftan, that is the more miraculous gold. In Pierre Wargnye’s expert hands, Le De (the name comes from the particule in “Hubert de Givenchy”) moves into a golden sunlight, pouring over a field of hay in early fall. It is the scent of tenderness, with a whispered diffusion.
