HELP!

So I know I posted that I found my dress, which I still do believe it's the one but a few days ago I posted a dress that I fell completely in love with, andddd I just found out it's a Maggie!!

but I can't find it anywhere!!! The picture of the dress is in my album. It's from a wedding I found on the vintageglamblog website.

Any clues on where I can find it?
