Fashion Design is one of the professions that creates high paying jobs in India for the deserving creative artists. INIFD REVIEW:
Placements: Placements are available but the quality of placements are not that effective. And the maximum Salary offered is around 30,000. Only 5 to 10 percent of students are selected in the interview. Roles offered to students totally depends on their capabilities and talent.

Fees will be INR. 50,000-60,000 as per college.

You can do a certificate in Textile and other fashion courses from government online institutes, I would recommend for Rapidskillz, as they have 1000 of online certificate courses and most of them they offer government approved courses. Few of my friends have done management and IT courses from there and they told me that they have fashion designing courses also in online mode.

Yes, you can opt for 1 year course also,for this you have to pay around 4 lakhs per year for this course from  INIFD, Indore. This fee is as according to the last year fee for this year, I'll prefer you to contact to college authorities for the exact details.
