I don't think it is too late. You are still young at the age of 30. You can do anything in time. As long as you really like fashion design and Zhen Chen has made up his mind, it's too late. If you make up your mind, don't regret it. You must stick to it. It's never too late to study, but you can't give up halfway. In the process of learning, no matter how difficult you encounter, you must grit your teeth and stick to it.
