You can tell your parents that it is your passion and you can’t force me for pursuing engineering. Make them understand the importance of FASHION in today’s scenario. This conflict majorly happens due to the age differences and this is very common, just be polite with them and make them understand about the new career opportunities. Because of their old thoughts they can’t match with the Morden changes and it will definitely take time to get them into these. But if you will be polite and gentle things will change soon. You can also convince them by saying that along with engineering you will also be pursuing you desire (FASHION). By doing this it will be easy for you to follow what you wanted to and their will not be much argument reading your career opportunities. And please don’t take your parents in wrong way they are concern for you so they will think wisely, also according to them pursuing Fashion will not secure you for lifetime; so it will be better to go with both these options.
