The base model is Velle, but I added and edited some clothes textures in GIMP!!
I'm not OP, the level of difficulty depends on the base avatar you choose, and what you're trying to accomplish.
Just posting an avatar designed for VRChat? Easy.
Adding clothes designed for your avatar? Relatively easy, but without dedicated tools time consuming
Making different clothes fit your model? That's Blender territory at this point
