I personally use Modular Avatar, it works with most clothing
Here's the dowload, https://modular-avatar.nadena.dev/
You should use Creator Companion with it so that it works properly
It's genuinely as easy as dragging the clothes onto your model, right clicking, selecting "Modular Avatar" and then hitting "Setup Outfit".
If the clothing comes with animations and has a menu it will automatically add the menu to your avatar. It's basically cheating so that you don't need Blender
