Yes, if you genuinely enjoy fashion, creativity, and designing, a fashion design course can be a great choice after 12th. Before enrolling, check what the course actually covers, whether it offers practical training, internships, and helps you build a strong portfolio.
Also, don't choose a college based only on its name. Compare a few options, talk to current students if you can, and see where graduates are working. AAFT University is one option you can look into while comparing different fashion design programs.
At the end of the day, your skills, creativity, and the effort you put in will have a bigger impact on your career than the college name alone.
