What is the best design software for creating a new clothing line?

I have many ideas for a new clothing line but I do not know which software to download to start up my ideas. I want something that I can design everything possible from shirts to jeans to jewelry and hats if at all possible. I am using a macbook pro and prefer something in which I can see a 3d model of my designs. What software would do the best job for me for a reasonable price or free?What is the best design software for creating a new clothing line?hi~~
