How does a fragrance celebrate its 20th birthday? With a blinged-out bottle and A-list celebrity, of course. Lancôme is pulling out all the stops to mark the anniversary of its prized perfume, Trésor, including a supremely limited-edition bottle of the classic juice. Twenty numbered bottles, with a special black diamond design, are being sold for 2,000 Euros apiece. Although these luxe limiteds aren’t coming to Canada, lovers of the classic rose-otto juice can always pick up the original bottle, inspired by a 75-sided diamond, at select Lancôme counters, $94 for 50 mL. Also part of the big occasion, spokesmodel Penelope Cruz stars in a 30-second ad for Trésor, due to start airing at the end of November. Set in Paris, the mini-film tells a classic romantic story, perfect for a classic romantic fragrance.
