History
Costume Liquide carries number 14.2 in Pierre Guillaume’s numbered collection, the one he first named Parfumerie Générale. Theme 14, “Iris,” gathers the compositions where iris root takes the lead. This is the house’s third work on that material: after Iris Oriental, a balmy iris, and Cuir d’Iris 14.1, a leathered iris created in 2007 that became a house classic, Costume Liquide 14.2, in 2023, offers a peppery rereading of it.
The project’s internal code name states the intent: “Iris Super-Ombré.” The whole perfume rests on that idea of shading. The iris isn’t laid bare: it is literally shaded by a “stormy” accord of pepper and peony. Pepper brings the bite, peony the floral tension; together they cast a dense shadow over the iris root, an enveloping preciousness that distills a sober elegance rather than a showy opulence.
The title, for its part, runs a tailoring metaphor. Costume Liquide is designed to bring the confidence, rightness and elegance of a tailored suit. The iris is the cloth here; pepper and peony are its cut. To open the accord, the perfumer calls on basil and violet leaves, which bring freshness and positivity; at the heart, the peppery iris takes its shadow from the peony, stormy and dense.
The base seeks the natural and the lasting: a superb quality of Haitian vetiver lays the foundation. That vetiver, smoky and rooty, gives the perfume its timeless classic finish: a stable base signature that anchors the iris without weighing it down. Released in 2023, Costume Liquide 14.2 thus closes the house’s iris triptych on its most structured version.
Fragrance notes
From violet leaf to vetiver root, by way of the peppery shadow at the heart.
The thread is iris: opened by violet leaves and basil, shaded at the heart by peony, and anchored by Haitian vetiver, which gives it its stability.
Scent profile
Costume Liquide is a peppery iris, dark and structured, the opposite of the powdery, light irises of tradition. The iris is treated as a cloth to be shaded: pepper and peony cast a stormy, dense shadow over it, making it an iris of shadow rather than light. Violet leaves and basil open it with freshness, peony casts its shadow, and Haitian vetiver anchors it in a smoky, rooty base.
It is a perfume of sober elegance, worn close to the skin and favouring rightness over projection. The sillage is measured, the longevity solid thanks to the vetiver base. An iris for those who love this material in its gravest, most peppery form, far from the cosmetic.
