One of my friends studied at Footwear Designing and Development Institute (FDDI). According to her, after 12th, usually students with Maths go for engineering, medical or CA. But ones willing to pursue a more creative career the FDDI is the place for you. 

Very few people go for FDDI. It offers other courses like leather goods and accessories design, retail and merchandising and fashion designing. These courses are the most popular at FDDI. But if you want to go into fashion designing then try for the NIFTs before FDDI.
