Is it correct to say "create fashion" as another way to say fashion design?

Yes, you can say "create fashion" to mean "fashion design" but it might not be as clear. "Fashion design" specifically refers to the process of creating clothing and accessories focusing on the artistic and technical details. "Create fashion" is a broader term that can also include styling and overall fashion creation. While "fashion design" is more precise and commonly used in the industry but "create fashion" can still get the idea across in a more general way.
