The image is a collage of nine photos of a white wedding dress on a runway. The dress is a ball gown style with a sweetheart neckline and a full skirt. It has a fitted bodice with a deep V-neckline and thin straps. The skirt is made of layers of tulle and has a train that flows down to the floor. 

The top left photo shows the back of the dress, which is a long, flowing gown with a train. The top right photo shows a model walking down the runway wearing the dress. The bottom left photo is a close-up of the back, showing the dress in all its glory. The middle photo shows another model wearing the same dress, but with a different angle of the skirt.

All the photos are taken from different angles, showcasing the dress and the model's back. The background of the collage is a gray wall with a floral design. The overall mood of the image is elegant and romantic.
