If you customize the class uniform and print someone else's brand trademark on it, it is definitely infringement. It is best to apply for a brand trademark of your own, so as to promote it in the future. If infringement is involved, it will also have an impact on future development, so it is best to have your own trademark. Now trademark awareness is very strong, and good trademarks are applied by others. Therefore, if you want to apply, you need to think about your trademark name and inquire whether you can apply.
