Really.
1. If there are no hangtags, they are all produced by small private factories. They are not fakes. Clothing factories only make clothes and are not involved in design. Each batch of clothes has specially supplied fabrics. Cloth has extra wastage, for example, 3% wastage, which means that each batch can produce three-thirds of products. If there are no defective products at 3%, the manufacturer will keep it and then use informal channels. Enter the market.
2. There are no labels because some brands are patented and cannot be sold privately. In fact, what you buy is the same as those with labels. It's the so-called original order.
