Looks like there's an interesting story to be told here. And I'm disappointed that you did not have a description here - but it's a really good way for people to make up their own stories.
I love the black and white contrasts of the stones and it's great that you kept a lot of the details on the dress.
I am a fan of selective desat, so the color and tones work well for me. I just don't feel this picture though. I don't know if its the mannequin or the barbed wire/christmas lights around the window, jmo.
The background does this shot in for me. I think I could probably go for the house type background but the Christmas lights ruin this for me. I like the presentation of the dress though.
I like the idea, but I think a better setup would have worked better. a different angle or something. My eye gets drawn from the dress to the window, because my mind is expecting to find a face above the neck, and instead there is the window. The colored shutters detract from the main focus of the image also.
