If I had to describe this outfit, I would say endless layers! And very difficult to model and texturize!
The reason for the difficulty was that the 2D image was far from reality, and since the modeling was done with software that simulates fabric movements based on reality (Marvelous Designer), this transformation had to be done creatively, and this includes most of the parts of the outfit.
Anyway, the final result is lovely in my opinion despite the difficulties and problems, and I hope you like it too.
