Striking images show most of the women in the audience covered head-to-toe, in accordance with Taliban dress policy, and holding Taliban flags.
Many also wore black gloves.
Several women spoke at the event in support of the Taliban, reports say.
"We are against those women who are protesting on the streets, claiming they are representative of women," said the first speaker, according to AFP.
"Is it freedom to like the last government? No, it is not freedom. The last government were misusing women. They were recruiting women just by their beauty," she said.
Another woman said she believed all Afghan women should wear a headscarf.
"Those not wearing the hijab are harming all of us," she said, according to AFP.
