Hello,

No, this won't be a good idea. If you are interested in fashion designing then the best way i would suggest you is that first complete your 10+2 and then prepare for NIFT or NID entrance examination.
Then you will be able to secure admission in top designing college and you will have options of various courses.You will also get placement in top MNCs if you will study in top colleges like NIFT.
So, in my opinion you must dream big, so complete your 10+2 first.

I hope this helps.

Dear Aspirants

Yes,But it's depend on your work, actually experience and studies both matter, you must have theortical knowledge as well as practical knowledge
It's depend on totally you how you present your design in front of interviewer

I hope you get my point

Good luck
