By its very nature, perfume conjures sensual collusion — between partners-in-crime drawn together despite themselves by its invisible, soundless siren call; between the scent and the skin that bears it; between the notes that conjoin to create a chimera. The downy bloom of an apricot cheek. The yielding softness of a white kid glove. The velvety warmth of a lover’s body. Skin to be nipped or stroked.
