Hello!

There is no such thing as a compulsory uniform for arts students. Every college decides that on its own whether they would want their students in casual dresses or uniform. Most of the colleges in Bombay don't have uniform in Junior college whereas the colleges in Navi Mumbai have uniforms for junior college students(11th, 12th). So it totally depends on the college you choose.
