1. There is no inevitable conflict between the two.
2. A trademark is a product or service provider that submits a trademark application to the National Trademark Office. After review, the National Trademark Office examiner authorizes the trademark. The owner's exclusive right to use the trademark
3. The brand name is a name given by the company to the product. It may be a registered trademark, or the trademark may not be registered or the trademark may be in the process of registration!
So the trademark of the clothes and the name of the brand are not necessarily the same!
