Hello Jyoti,

Interior design is a branch of design that covers the designing of the interiors of a room or building. It includes the development of a concept, up to the actual execution of the design. Your degree will expand your understanding of the human need, user experience, site context, and culture.

Fashion designers create original clothing, accessories, and footwear. They sketch designs, select fabrics and patterns, and give instructions on how to make the products they design.

Both are totally different fields with different requirements. If you have a good knowledge of that field then you can earn a good amount of money.

Hope it helps you

Thank you
