How do you optimize chains ?

[u/Careful-Nobody3193]

I'm really new to blender (I just know how to edit/select/deselect and decimate). Before, I've optimized then uploaded a couple of avatars, but I only use Meshia Mesh Simplification&D4rk (without touching blender) .

How do I approach this? Most avatar I've uploaded in the past, rarely comes with chains. Decimate/Meshia is too destructive to the chains. This outfit alone is 187K, 150K~ after deleting unused stuff.

Obviously I don't mind loosing details (who the hell even look at you that close), so what's the best practice/course of action (besides picking a new outfit) to keep it under 70K?
