Anthropologie and Express have joined the list of top international retailers banning mohair following a PETA video exposé of the industry.
Other big names promising to eschew the material include Topshop, H&M and Gap following the investigation by the leading animal rights charity.
Investigators visited 12 farms in South Africa - the source of more than 50 percent of the world's mohair - in January and February of this year. They uncovered a litany of abuse, including workers dragging goats by the horns and legs and lifting them off the floor by the tail, which could break their spines.
Footage from PETA's investigation
According to PETA: "Anthropologie received more than 18,000 letters from PETA supporters before it announced that '[due] to the potential for the mistreatment of animals', it won't buy or produce mohair products as of March 2019.
"After hearing from PETA, Express also announced that it will not sell items containing the cruelly obtained material.
"They join Arcadia Group, H&M Group, Inditex apparel brands, Gap, Athleta, Old Navy, Banana Republic, and numerous other brands that have gone mohair-free - and PETA is now calling on Forever 21 to follow suit."
'Blood and cries'
PETA Director of Corporate Affairs, Anne Brainard, added: "No sweater or scarf is worth the blood and cries of gentle baby goats.
"PETA is calling on Forever 21 and all other retailers to join Anthropologie, Express, and other top brands in refusing to support the cruel mohair industry."
PETA has asked law-enforcement agencies to investigate and file charges, as appropriate, for potential violations of South Africa's Animals Protection Act, 1962.
