Before the air around Chloë Sevigny can be spritzed with her rose-scented perfume, it must first be cleared.

Ms. Sevigny gasped when she learned that some people interpreted a remark she recently made on Instagram as passive-aggressive.

“Always nice to be included,” she had written beneath a Variety magazine cover that she shared with Kim Kardashian. They had been paired for an “actors on actors” conversation, which Variety released online on Wednesday.

“Because I just come off as snarky?” Ms. Sevigny laughed. “The inside scoop is I wasn’t supposed to be there.” She had replaced another actress who was sick with Covid. And she was grateful to be included.

“I would like to have bigger parts in bigger movies,” said Ms. Sevigny, who wants to be perceived as a “character actor.” This year she starred as the midcentury socialite C.Z. Guest on “Feud: Capote Vs. The Swans,” a series on FX and Hulu. She just finished filming another series, playing Kitty Menendez, who was killed by her sons in 1989. The day after our interview, she was set to fly to San Francisco for rehearsals on a new Luca Guadagnino film, co-starring Julia Roberts and Ayo Edebiri.

When we met, Ms. Sevigny, 49, was sitting in front of a mirror and having her hair wrapped into a tight bun. She wore a striped robe and gem-encrusted Crocs by Simone Rocha. She was preparing for a cocktail party being thrown that evening on the roof of Fouquet’s New York for her fragrance, Little Flower, made by the indie perfumer Régime des Fleurs.
