“We talked a lot about what this should be — thrilled that was the decision we made,” Parker says of her and stylist Pat Fields’ decision to dress Bradshaw in the white tulle skirt and pink tank top for the show’s opening credits. “I would never wear it myself personally, but it’s spot on.” And the outfit remains so special to Parker that she just reinvented the style in LBD form for her SJP Collection.

Parker goes on to discuss the Galliano newsprint dress (which they had to “beg” to get back for the first SATC film), her sequin runway panties and the multicolor skirt that she wore while secretly pregnant with her son James Wilkie.

“The skirt kept blowing up,” Parker says of filming while pregnant, adding, “I was so afraid when my skirt blew up that you would see — no one knew at work, and there was paparazzi everywhere.”

And of course the massive Versace gown that “was the dress we had absolutely no reason to use,” according to Parker. Bradshaw famously falls asleep in the confection while waiting for “Alexander the Great” at her hotel room in Paris.

“It took four or five people that had to help me walk to the set,” she shares.
