TAKE THREE: Nina Ricci will tease its new fragrance, Nina L’Eau, starting Saturday on Facebook. The brand’s scents already have more than two million fans, making it the largest fragrance-related community on the social-networking site, according to the company. Lensed by Eugenio Recuenco — who also filmed the campaigns for the two prior Nina scents — it features model Frida Gustavsson wandering in a snowy labyrinth before finding the apple-shaped scent bottle. She wears a Nina Ricci dress created especially for the spot by the label’s designer, Peter Copping. The ad is to appear in 30- and 50-second takes destined for television and movie theaters, as well.
