NIFT

Hi,I hope you are doing good. This might be a late reply since you posted your question 2 months ago.
What's making you change your stream of carrier? you want to continue in the fashion designing field or move back to software once you finish your degree?
If you're really interested in fashion designing, Go full-time. I don't think they offer part-time courses.
Assuming that you have done your Bachelors, Here are Postgraduate options for you: after BTech, you can do M.Ftech(master of fashion technology) or M.Des(master of design)
- For M.Des,you are supposed to have a diploma in design(from NIFT or NID's) or any other undergraduate degree.(12th+4 rule).
- For M.Ftech, you should have a BE/Btech degree or undergraduate degree from NIFT or NID's.
- CEED, which takes admission through GATE is only for engineering designing. If you are interested in apparel designing.
- For other designing fields like interior designing and industrial designing. Your BTech degree will help.
Hoping that this will help and you take the right decision.
Thank you,
RJ

Yes, you can do M. Des from NIFT on the basis of B.Com. The eligibility criteria for M. Des course is given below:
1. Educational qualifications: Undergraduate Degree in any discipline from any Institute /University recognized by law in India. or
Undergraduate Diploma of minimum three years duration from NIFT / NID.
2. Qualifying Age: No age limit
Note: Master of Design (M. Des. ) is an advanced course that demands an understanding of fundamentals in design and presupposes that candidates would be familiar with the basic skills and theories for successful completion of the programme. The course would not provide any basic knowledge and skill development in design as a part of its Masters programme.
