Unity Model Clothing

Hi,

I'm really new to modelling and have created a basic humanoid model with no clothing or hair in Blender. I'll be rigging it for use with Mecanim and then I'll be wanting to add equippable clothing.

I really just need to know the best way to go about this. For instance, I'd want to make an open jacket for the model. My assumption is I'd create the jacket on the original model with the same rigging and then export it without the original model. From there I am unsure of how to "equip" it onto the original model in game (if the method of creating it is even correct to begin with).
