Does Anyone Know Who The Designer Is Of This Dress?

Does anyone know who the designer is of this dress?

I know it is a Pnina Tornai inspired gown. The Pnina version of this dress is around $20k and I saw this picture on an Ebay auction, and I wanted to know what the designer is of it so I can see how much it costs.

Thanks so much!
