In Leather di Etienne Aigner è una fragranza del gruppo Floreale femminile. Lanciato sul mercato nel 2003.

Directions for use: Spray the perfume by placing the bottle at least 12-18 cm away from the chest or body. Point the nozzle at the point where you will vaporize it. If your skin gets wet when you spray the perfume, the bottle is too close. For a more perfume decided, apply the perfume on the pulse points: neck, nape, wrist, forearm and behind the ears. Vaporizes in the void and crosses the perfume cloud for a more delicate result.
