Gold dominated, shimmering across a cape, on a breastplate and popping against white and black accompaniments.
Long yellow and orange ponchos handsewn in Uruguay and red pantsuits also brought to mind the colors of fire.
Some pieces appeared to have been directly molded onto the models with the collection notes describing how leather had been soaked in water and then draped over a form to create unique pieces.
The theme of women's empowerment was also woven into the show.
Hearst, who is also the creative director at Chloe, said her 2023 Ready-to-Wear Collection was inspired by the ancient Greek poet Sappho and how she had shed light on the hardships women had to endure.
"This Joy," a gospel song written by Grammy winner Shirley Caesar, was performed by the Resistance Revival Chorus, which was billed as a collective of women and non-binary singers that addresses how "historically marginalized women have been in the music industry."
The catwalk cast included women's rights activist Cecile Richards, Mexican Chilean climate activist Xiye Ba and anti-toxic shock syndrome campaigner Lauren Wasser.
Hearst also said she had aimed to offset the climate footprint of her show by working with Swiss company Climeworks, which uses technology to capture carbon dioxide directly from the air.
