Actress and activist Jane Fonda has pledged not to buy "any more clothes" in her effort to fight climate change.

Fonda, during her weekly "Fire Drill Friday" climate change protest on Capitol Hill last week, made the declaration that the coat on her back was the last piece of clothing she would ever purchase.

"You see this coat? I needed something red, and so I went out and found this coat on sale. This is the last article of clothing that I'm going to ever buy," she said in footage captured by video journalist Nicholas Ballasy.

Fonda then attributed credit to youth climate activist Greta Thunberg for making her "think a lot about consumerism."

"I grew up when consumerism didn't have such a stranglehold over us, so when I talk to people about how we don't really need to keep shopping, we shouldn't look to shopping for our identity, we just don't need more stuff, then I have to walk the talk," she said. "So I'm not buying any more clothes — it gives me a lot of free time."

Fonda, 81, was arrested Friday alongside actresses Rosanna Arquette and Catherine Keener, both 60. The incident marked the fourth week in a row that the actress found herself handcuffed during the climate change protest. It was, however, the first time she went to jail afterward.

A spokesperson for Fonda told media outlets that the actress would be "spending the night in jail" and was set to appear in Superior Court at 10 a.m. on Saturday morning.

In October, Fonda pledged to get arrested every week that she holds the organized demonstration.

"I’m going to take my body, which is kind of famous and popular right now because of the series, and I’m going to go to D.C., and I’m going to have a rally every Friday,” she said after her first arrest. “It’ll be called ‘Fire Drill Friday.’ And we’re going to engage in civil disobedience, and we’re going to get arrested every Friday."
