You thought you'd have to wait until Thanksgiving to hear the rest of the viral wedding dress story. It turns out that bridal shop owner Kasia waited quite some time to tell the story, so as not to let the cat out of the bag, so to speak. The wedding was last Thanksgiving, and is all done with now. In part three, which had to be posted because everyone has been waiting for the rest of the story, Kasia tells how the bride wanted a different dress anyway, for a completely different reason.
But that's not all there is to the story. There seemed to be a meaning behind all the shenanigans.
