What is the best way to create character customization?

Hi Guys, I need to create a character customization system in unity. I have a basic idea about how it works, meaning, but if I use separated parts like hair style, clothing, accessories and stuf, that should deform accordingly to the character's movement, is it possible?

Is there any kind of morphing besides the standard morph targets to help the clothes to adapt to the rest of the base model?

I know that I can parent certain accessories to certain bones and makes it move with the body wihout deformation, but to achieve a complete character system, the clothes need to be poligonal.

Any advices?

Thanks!
