Fashion Design

Both have equal scope.

The course related to fabric and garment manufacturing is basically fashion designing, like for Bachelors it is B.Des. in fashion designing and for Masters it is M.Des. in fashion designing.
In this, you'll be taught about the fabric and garment manufacturing in detail. If you just want to go with the fabrics then you can do something with textile designing and that is also a good option with a lot of scope.

Yes, you can pursue Masters in fashion designing. To get into a good college such as NIFT or NID, you need to appear for their entrance exams, so start preparing for the same.

I would suggest you to go for a degree course, as that has more value and will help you get better job prospects.

The main objective of internship is to get the practical knowledge of the industry. It is always better to go for as many internship as possible because it will give you the industrial experience, which will definitely help you in your future.

No, it is not necessary to do fashion design.
