VeganShoeLady says knockoffs aren’t vegan:
…no matter how fake the leather/fur/wool/silk might be…. In recent years, most knockoff goods have been made in shady conditions (read: sweatshops), often by child workers. In Deluxe: How Luxury Lost Its Luster, Dana Thomas describes an account of Thai children whose legs were broken to keep them from going outside to play while they were supposed to be making fake handbags…. Being vegan is about reducing suffering. When you buy fakes, you are giving your money to people who are actively making the world worse.
