Animal-rights charity PETA called on the company, which has recently filed for bankruptcy amid the coronavirus (Covid-19) crisis, to use 'animal-friendly materials'.
"Today's compassionate shoppers look for products that are kind to animals and the planet, so wool and cashmere just don't make the cut," says PETA Executive Vice President Tracy Reiman.
"PETA is calling on J.Crew to leave cruelty to gentle sheep and goats behind as it reevaluates its business practices."
PETA added: "[The brand] has led specialty retail by 'putting the consumer first and at the center' and consumers, now more than ever before, are looking to brands to do the right thing.
"That includes acting responsibly toward animals and the planet. In fact, vegan clothing, accessories, and footwear saw a 54 percent increase at US retail stores in the first half of 2019."
