Saving parts/models with DataStore?

I am making a character customization system where you would customize your character and then when you would press done, it would save your character. Some of the assets are models that are CFramed and welded onto the character.

Thing is I don't even know how to data save parts or even models. I know this isn't a demand site. But I'm not looking for scripts or anything, I just need an idea on how I would go about this. I've heard of a HumanoidDescription System, but it isn't necessary what I was looking for.

You cannot save instances to DataStore. Instead, you have to save every single property to it.
