i made this model based on a character design i did for artstation challange neotokyo.
i thought it was a cool design so i made some changes and made a 3d character out of it.

its rigged with Rigify but for the cloth parts you have to run a cloth sim.
i made a preset for the Dress and the Cape which i think works good enough for most occasions.
i recommend you keyframe your character on the rest pose and give it 30 frames or something before your animation to give the cloth sim some time to adopt to the characters pose before animation.

Verts: 249,316
Faces: 243,097
Tris: 482,234
Objects: 49

i recommend not joining the objects together, because you can subdivide them individually where you need more detail at the time.
and definitely don't merge the cloth parts because you need them to be simulated with cloth sim.
