The burning fashion question over at Gap these days is: "How do you wear it?" If you're Sarah Jessica Parker (search), the answer is: with velvet ribbon and bows.

Parker stars in the retailer's fall marketing campaign, and for her ads, the "Sex and the City" (search) actress customized several pairs of jeans. On one pair, she added a velvet ribbon sewn down the legs to imitate tuxedo pants. Another one of her customized looks features jeans cut just below the knee and enhanced with a ribbon bow at the hemline.

She dresses the jeans up and down with her tops, including a shrunken jacket, a sexy secretary's pink cardigan, a black turtleneck and a white button-down shirt with black piping, to which she added a bow tie.

"I think the Gap is terrifically creative, fun, inspired, and the clothes are for everyone, of every age," said Parker, known as a fashionista both on-screen and off, in a statement e-mailed to The Associated Press. "They are timeless, easy, colorful, classic and affordable."

Parker describes her own style as having "no rules." She's been known to wear vintage, off-the-rack sportswear and couture — sometimes all at the same time.

"For 35 years, Gap has embraced individual style. Asking the world, 'How Do You Wear It?' is an invitation for personal expression and a conscious effort to connect the brand more closely with customers," said Gary Muto, president of Gap, in a statement Monday.

"Sarah Jessica Parker's innate sense of style is so dynamic and unique that she is the perfect fit for our fall campaign," he said.

Other celebrities to be featured in the print ads include Jada Pinkett Smith, Jessica Alba, Lenny Kravitz (search), Michael Vartan (search) and Peter Krause (search). Kravitz stars with Parker in the TV campaign, which will debut during the MTV Video Music Awards on Aug. 29.

Gap customers will have a chance to customize their own jeans at in-store events in select cities from August through October. The "Show Us How You Wear It" tour also will bring a traveling studio to stores, where customers will be able to have their photo taken that will look like a real Gap ad.
