Match Kaya's outfit in "Node of Schezero" with stock photos?

[lavenderspikes.livejournal.com]

Hello!  Yes, this is a picture request.  I am making a cosplay commission of Kaya in Node of Schezero wearing a gorgeous lolita ensamble, but am unable to find clear pictures of the outfit my customer wants.  It occurred to me that Kaya does a lot of stuff with BtSSB, and that what he's wearing probably is something they produced and that better pictures do exist! (I pray).  Does anyone have any stock photos/other photos of this:

It's definitely a bustier/skirt combo with shirring in the back, and I think I can manage the skirt without further pictures, but I could really use something for the bustier.  Stock pics or pictures of the actual bustier if you own it would be awesome!  I would really love a closer look at the fabric they used on this

If it turns out that this is a one-off piece or it isn't really BtSSB I apologize but I would really appreciate help as I'm having no luck at all on my own.  Even if you just know the name of the pieces that would be great :)  Thank you very much!
