It depends on the specific situation. If you replace someone else's brand on the clothing with your own brand, it is also an infringement and is called reverse counterfeiting. For example, if you remove the trademark of Li Ning Clothing and replace it with your own trademark, it will be considered an infringement. Of course, the other party must have sufficient evidence to prove it.

If the clothing factory has not yet OEMed the label, and you put your own brand on it, it generally cannot be considered as infringement.

If the factory is OEM for the brand, the contract between them will generally prohibit the OEM from processing for others. If you wholesale from such a manufacturer, the risk is relatively high.
