Exclusive: See The 'Extreme' Fashion Of 'Confessions Of A Shopaholic'

Star Isla Fisher and stylist Patricia Field discuss the very original look of Rebecca Bloomfield.

In an exclusive featurette about the making of [movie id="367357"]"Confessions of a Shopaholic"[/movie] (which opens on February 13), the cast and crew divulge the inspiration behind the movie's designer gleam.

"Sex and the City" stylist Patricia Field created the costumes to reflect the fashion-forward energy of New York City, where the story of journalist Rebecca Bloomfield ([movieperson id="287406"]Isla Fisher[/movieperson]) unfolds.

"New York is literally the fashion capital of the world," Fisher exclaimed, "and there are so many brilliant stores."

Director P.J. Hogan took full advantage of shooting on location in Manhattan. "We shot in Bendel's, Catherine Malandrino's, Barney's," Hogan boasted.

"Rebecca has an original style," he added. "She doesn't dress like anybody else."

Field, who is known for creating over-the-top outfits for [movie id="355798"]"SATC"[/movie] and [movie id="285454"]"The Devil Wears Prada,"[/movie] certainly wasn't expected to make Rebecca look like anyone else.

"It's just a little eclectic mix of something cute, something designer," Field said. "It was an opportunity for me to create a different look for people to see that they haven't really seen before. It's fashion-forward but an exaggerated for this extreme character who can't stop shopping."

And Fisher jumped at the opportunity to work with the fashion icon. "I wanted Becky to be adventurous and bright and colorful but at the same time high fashion," she said. "It was so much fun creating her with Patricia Field. She's such an amazing designer and she has such a unique vision."
