As Hollywood studio exec Ellie, Tea Leoni works a tailored, sophisticated look that becomes more casual as her character finds happiness in NYC. ''She's sort of a fast-talking [L.A. type in the beginning],'' says costume designer Melissa Toth. ''But she's still a romantic and a New Yorker at heart, so I wanted to show a journey [in her style].'' By movie's end, Leoni has hung up the high-powered Barbara Bui pantsuits she wears during early business meetings for Hepburnesque ensembles by Faconnable.

Reality Check: Would an actual studio exec greenlight the outfits? ''It's a fair portrayal,'' says a 20th Century Fox studio rep. As for the $900-$1,200 that similar Faconnable and Barbara Bui items cost, no sweat. A real-life Ellie's salary can be up to $6 million per year. Leoni's Clothes Call Rating: 4 Hangers
