Designer Stella McCartney will launch L.I.L.Y, her second pillar fragrance, in 2012. The name comes from her father Paul McCartney’s nickname for his first wife, Linda McCartney (Linda I Love You). It also references the new scent’s lily of the valley note; according to Stella McCartney, L.I.L.Y explores that note’s “darker, more masculine side”.

L.I.L.Y was developed by perfumer Jacques Cavallier, who also created the designer’s popular Stella fragrance. In addition to lily of the valley, the fragrance notes include truffle and oak moss.

Stella McCartney L.I.L.Y will debut at Selfridges in January; it is not expected to reach the United States until September 2012, when it will be available at Sephora. It will be sold in 10 ml roll-on ($25), or in 30, 50 or 75 ml Eau de Parfum ($60 – $100). Matching body products will also be available.
