After some careful consideration I thought it would be best to make the tail-bow (I don't know what else I'm supposed to call it?) attached to the sash. Sash-tail-bow. Yes.
I don't have a photo of this but I cut a piece of interfacing that was attached to the pleated sash. I backed the sash with the corduroy from the jacket and skirt cape otherwise the sash just by itself would be too flimsy.
I bought bridal satin in a baby pink color and cut the pieces for the bow. I also put some interfacing in these pieces to make them more stiff.
I was blessed again to find faux fur in the exact texture and color I wanted, at some random fabric shop in the fashion district. I bought a yard at 60" width.


I stuffed the sewn pieces with polyester batting, which is always pretty helpful to keep around for cosplay projects. You can get a pretty big bag for under $10, worth it.
You can see that some of the fur got caught in the seam--no worries, just scratch your fingers over the seam and the fur is released from the seam.
Once I finished the fur pieces I simply hand sewed everything to the pleated sash, and used large snaps for the closure.
