Question Customizable 3D character component(s?)

I am new to Unity and wonder what is the ECS/DOTS way to customize a 3d mesh?

By customize I mean for example offer a wardrobe, let the user chose clothes to put on the character. How would that work in a ECS? Lets say that every clothes is a 3D mesh, I must somehow store these clothes in a component. There must be a head slot, body slot, legs slot and so on. What data type should these slots be?

Or should I make one component for every clothes and then "tag" these on the character? So a character is essentially a base model component, head component, body component, leg component and so on. How would I get all this to follow the character as it moves?

Do anyone have a good sample code for this? I cannot find anything useful from my search terms.

EDIT: I _think_ that I am wanting something like in this example: https://github.com/DapperDino/Multiplayer-Character-Select/tree/main but for DOTS.

UPDATE: Okay I think I grasped the basic concepts. In this post https://forum.unity.com/threads/how-to-create-procedural-meshes-at-runtime.1436287/ they talk about Procedural Meshes, not really what I am trying to achieve. But, what is interesting here is that you can generate a mesh in ECS, maybe I can use it to load a mesh and append it on my character somehow! This is also a good place for mesh generation: https://github.com/Dreaming381/Latios-Framework-Documentation/blob/main/Kinemation Animation and Rendering/Dynamic Meshes.md

Here is how you can "Weakly reference an object" https://docs.unity3d.com/Packages/c.../content-management-get-a-weak-reference.html Hmm... And here is how you can "Load a weakly-referenced object at runtime" Hmmmm..... Whats interesting about this that I could store a mesh in an Component. So if I have a number of hats, I could create a HatComponent and then change the hat via a
WeakObjectReference<Mesh>

This is far from a complete solution, I will keep on tinkering about how all of this can be put together.

UPDATE2: Here is something called submesh! It appears needing ye olde GameObject through! https://github.com/Unity-Technologi...RPSamples/Assets/SampleScenes/6. Misc/Submesh
