RPG animation system

Hi! I want to have a system where I can switch out clothes on my character (body parts) and have an animation system that allows me to do this.

Currently I have a complete set of body parts in blender, I have them rigged up with automatic weights, and a replacement test body part (I have 2 heads and will use one head to replace the first). Where do I go from here?

(I ask this because Im quite familiar with tutorials on how to set up animations for a single body mesh that doesn’t change, and Im not too concerned about those, but I couldn’t find much information on how to set up an animation system for interchangeable clothes)

I figured out what to do:
Make sure to parent the rig to the new replacement body part/mesh with automatic weights (or some alternative method of parenting) in Blender
Then when you import the wanted replacement part, make sure it (from above step) was parented to the same rig as the original body parts
2 that it has a skinned mesh renderer
3 that in that skin mesh renderer the root bone is either the root bone for the rig or the bone for the body part you are replacing (depending on how you parented the replacement body part)

(If you run into errors, make sure you already got your imported blender rig to pass muster with unity, unity accepted it, its in a t-pose, and all of the bones are in their respective humanoid counter parts on unity)
