Recently, the founders of an Instagram account called “Every Outfit on Sex and the City” threw a fund-raising bash for Cynthia Nixon’s campaign for New York governor . They kicked it off with some softballs for the crowd: Team Aidan? Or Team Big? Then, they ushered in Ms. Nixon.

At first, the candidate was sharper on politics than she was on Miranda — to be fair, it’s been eight years since “Sex and the City 2” — and she seemed concerned that the hosts were mocking the character.

But Ms. Nixon soon found the pulse of the event and began to dish, telling stories of outfit choices she had made — a neck scarf that Miranda wears during a speed date was her idea — and scenes that never made it to air. She described with gusto the episode in which Miranda eats cake out of the garbage, explaining that she and the director, Allen Coulter, had shot an alternate take as a homage to “Psycho,” with Miranda eating the cake in a frenzy, smearing it all over her face and, finally, collapsing and dragging her hand down the refrigerator, leaving chocolate streak in its wake. (The scene, sadly, is not yet available on YouTube.)

She was also fully prepared for a question about the more problematic aspects of the show.

“‘Sex and the City’ started 20 years ago, and I’m very keenly aware of this,” she said, adding that one of the chief failings of the show was its focus on “a very, very thin slice of an extremely white and extremely affluent part of New York.” And while she called it a feminist show, she said that “the flaws of the feminist movement are reflected in ‘Sex and the City,’ too.”
