Was this purchased at a retail store or was it handmade?
In Houston we have a place called High Fashion Fabrics, and I swear if the fabric isn't in the store, you don't need it! If ever I wanted to pay $400 a yard for fabric, this is where I would go. I once bought a formal dress and I wanted to put long sleeves on it, and believe it or not, I found the exact fabric at High Fashion Fabrics!
Here is their website. They don't show everything they have, but their contact information is included - perhaps you could email this photo and they might be able to help you.
