Get ready to be knocked out!

Three hundred wardrobe changes and 81 outfits for SARAH JESSICA PARKER alone! Fab Four KIM CATTRALL, KRISTIN DAVIS, CYNTHIA NIXON and Sarah Jessica joined OPRAH WINFREY on her talk-show Thursday to share fashion and set secrets from the upcoming 'Sex and the City: The Movie' -- and after seeing the movie, Oprah declared the outfits are better than ever!

"The movie doesn't disappoint!" said Miss O, who got to see a VIP screening of the film along with her Chicago studio audience. "It certainly doesn't disappoint in fashion."

Famed series stylist PATRICIA FIELDS returned to dress the ladies for the movie, and described the significance of the white flower dress (above) that Sarah Jessica is seen wearing in the ads and the opening scene.

"Of course, everybody remembers the flower from the show," Pat says. (Fans know that Sarah's character Carrie is known for wearing oversized flowers on her outfits.) Pat explained that this very special dress is a "vintage gown that I shortened into a minidress." 

She also reveals that "belts were very, very important" in the look of the new movie. "I think it's the new silhouette," she predicts. 

'Sex and the City: The Movie' opens in theaters on May 30, and ET's 'SATC' movie exclusives start Monday, May 5!
