First, if you are afraid of infringement, change the prototype and register your own copyright. You can also sue others for selling the intact product.

Secondly, you cannot prevent others from imitating your products. The only way is to register your own trademark to protect your brand. There are many versions of the same clothes from different brands, and the price of each brand is different. So do you want to make a high-priced one or a low-priced one? Therefore, posting your own registered trademark is the best way to protect your rights and interests
