The blue mirror composition shows a large upper X across the back, with several finer crossings below it. Central tied ends sit before the long skirt begins. The reflective-looking fabric spreads in broader folds on the floor. In the mirror, a front V line, a leg opening and part of a pale shoe are visible. The reflected hands rest together in front of the body rather than clearly pulling the skirt sideways.
Compared with the close blue rear view, this image adds information about the relationship between back, front and lower silhouette. Small reflected areas still have limits: the front upper edge is reduced in size, the shoe is incomplete and operation of the ties is not demonstrated. Similar colouring does not replace examining the actual offered model.
Use the image to consider whether you also want a front leg opening alongside the open back. Have both views of the real dress shown at normal scale. Choosing length requires a fitting in your intended shoes, with the skirt falling freely rather than being specially arranged across the floor for a photograph.
