Hello aspirant,
If you are sure about doing only fashion designing only then you can take arts so that you have less burden as other subjects are difficult little bit.
Fashion designing is a course that needs creativity, ideation, critical thinking, knowledge about trends and other skills like sketching and rendering.
There is no restriction as to which stream you should choose in class 11. You can take any stream of your interest science, arts and commerce.
Hope this helps you
All the best for your future
