What is the cheapest way to make clothes?

I am asking this question since the 4.18 has enhanced features for the clothing stuff.
I am not a 3d modeller and I have no clue how to produce an humanoid 3d model, worse for the clothing.
But with external tools like Adobe Fuse and Mixamo, it’s extremely easy to produce at least a custom humanoid where you can apply basic clothes.
But what about custom clothing? Is there a simple way to create custom clothes without specific 3d skills?
