dear student

Both these courses are totally contrary to each other.

You need to have  different set of skills in order to excel in them.

If you are creative enough to bring your thoughts and ideas into reality, you are good for B.Des. However, there is nothing like, you can’t opt for B.F.Tech instead.

Now, if you have a technical mind and you are interested in apparel production, you should totally go for B.F.Tech. Also, you need to have PCM in your 10+2.

B.DES requires more of creativity, artistic mind  and you end-up as a designer in some company or in a boutique   

B.F.Tech is more like theories and factory manager job and you will end-up knowing everything to start a garment manufacturing company or to work in one. 

Choose your ways wisely!

hope it helps

All the  best!!!
