Hello Sanjana

There are lots of Universities in Italy for designing so you have to be more specific about the university.

Here I'm telling you about Florence institute of design international, university in Florence,

For financial aid you have to submit your 10 projects( no group projects), and your portfolio.

You have to clear your English tests also and have to submit everything before the starting of academic session.(usually before 90 days).

For admission you have to check for the release of admission forms regularly, after you get selected you can apply for visa and also for financial aid( scholarship).

You will get atleast 25% financial aid.

For most of the Universities same rules apply so you can try for different universities.

I hope it helps
