There are courses available in NIFT and other reputed institutes in the above domains. Try and research more about it. Some will provide you with a bachelor's degree, but at this time I would suggest you to do a masters in fashion management/Diploma in Fashion management/Fashion Communication.
Since you have an engineering background, I would suggest you to look at design courses in NID, their curriculum and eligibility. If you can manage to crack their masters level entrances, it would prove to be a huge boost for your career in fashion.
Lastly, I hope you have thought about your choice regarding choosing the field of fashion, because after this level (postgraduate), it would be very difficult for you to change your field again.
I hope you now understand that a fashion in career would give you great chance to indulge your creativity and skill.
