Decisions, Decisions For a breakfast meeting at the Peninsula (is that Denzel?), lunch at the Bel-Air (oh, my God, Jack Nicholson) and a seminar on Foot Odor and the American Male, her travel pants are reunited with their jacket ($695). The silk nightie ($260) is by Prada. Day 1: N.Y. to L.A. With six easy pieces and a pair of shoes packed into her Christian louboutin carry-on ($995), our fragrance executive boards the 9:30 P.M. flight to LAX. She's wearing a cashmere tank top by Marc Jacobs ($770), a Paul Smith cardigan ($240), capri pants ($350; part of a Barneys New York collection suit) and Sergio Rossi mules. Holding her Guy Laroche leather coat ($4,060) and Christian louboutin train case ($825), she's headed for the Mondrian -- where else? Day 2: Some Enchanted Evening Thanks to the miracle of modern chemistry, this stretch-rayon gown($370) by Ann Demeulemeester can be worn to the Golden Nose Awards without even a pressing. Her clutch is by Guy Laroche. And the wrapped cardigan is so L.A. Day 3: Breakfast Of Champignons Today she's wearing the cardigan with a wool skirt ($675) by Marc Jacobs for an early business meal (skillet- scrambled eggs with mushrooms) at the Four Seasons (cool!). Her spikes are by Sergio Rossi. And the laptop is a rental. Day 3: Blind Ambition A blind date at the Ivy. (He's a New Yorker with a development deal who talks too much.) A nightcap at the Formosa. (Hey, that's Quentin Tarantino! And he's making out! And it's not Mira Sorvino!) And a good-night kiss, all in the Marc Jacobs tank and skirt. Bliss. Day 3: Spree at Last! The fun begins at the Getty, followed by lunch at In-N-Out Burger and pit stops at Trashy Lingerie and Maxfield. Looking sufficiently Melrose in her capri pants with an Isaac tank top ($39), she feels right at home in the back seat of Music Express car service.
