Shalimar Ode à la Vanille is an oriental developed by house perfumer Thierry Wasser, and features vanilla from Madagascar and Mayotte that has been infused for 4 years. Other notes include lemon, bergamot, rose, jasmine, iris, incense, opoponax and tonka bean.
Guerlain Shalimar Ode à la Vanille will be available in Eau de Parfum, in the new bottle designed by Jade Jagger, £61.50. I will update with the size when I find it. (via diarydirectory.com, parfums-tendance.fr)
