This is a YAB+ Large upscale of the "Arachne Bolero" vanilla body piece.
I also removed the sleeves and cape entirely and the bottom part of the undershirt to give it a bit more of a "sexy" look. The real motivation there is that it makes the upscaling much easier, but I also think it looks better this way and allows expression of your WoL through tattoos that are no longer covered up.
