Possible dress dupe

I was browsing when I found this. A possible dupe for the dress Katherine wears in the masquerade. It would need to be touched by the hand of a skilled seamstress, to make the neckline accurate, but other than that it's pretty damned good. Has the texture and length correct. Just needs a ribbon sash and it would be a near 100% match. Price is 389.00. While close(very close) it is expensive for a garment that will need to be modified. I'll continue looking.
