You can look at the wash mark. And the texture of the clothes. You can also go to the official website to see if this product is available. If it doesn't have a tag, it doesn't necessarily mean it's fake. Reasons: 1. It was worn by someone else and the label was cut. 2. The so-called original order means that the goods were obtained directly from the manufacturer. This kind is usually given to the factory without playing or cutting the cards. 3. Defective products. In fact, if you really like it, it doesn’t matter if it’s fake or not. You don’t necessarily need to know the brand of stuff.
