This Taliban group stormed into shops in Wana in South Waziristan, and made a bonfire of the cloths in a public area near the bazaar, officials said.
According to Rahimullah Khan, a shopkeeper, at least eight armed men burst into his premises and took away bundles of raw cloth saying it was too thin to make respectable clothing.
"They said it was un-Islamic to wear clothes that don't properly cover the human body," the Dawn quoted Khan as saying.
An anonymous official claimed that the perpetrators were local Taliban, adding that shop-owners calculated thousands of metres of material have been destroyed.
Taliban militants in Pakistan have often targeted shops selling music and films that they claim to be violating Islamic moral codes.
