Looking For Elizabeth Fillmore "Isabelle"

I was recently at an Elizabeth Fillmore trunk show and fell in love with her "Isabelle" dress. She was amazing and I felt like a goddess, but the dress was out of my price range. If anyone knows were I can find this dress, or even others like it, at a better price (new or used) I`d be most appreciative. Also, how would I find out the style number? Thanks!!
