Programs you need to know for Digital Fashion  

3ds max, marvelous designer, zbrush, substance painter/photoshop. Learning unreal for rendering.

if you're an actual fashion designer(a rookie) the most important part is the material you're using

I mainly use blender, I personally have been skeptical about using other programs like daz or marvelous because I haven't seen the topology on them, I've mainly seen how they're very heavy on using cloth like simulation to fit or create things. They do look beautiful though

How much do the jobs pay ?

this look cool but what if i wanna make it more physic ? well it break the cloth? so how to do that
