A pale narrow party dress has fine straps, a shaped-looking upper edge and a long skirt opening over one leg. Bright points cover the surface. The front view clearly shows the relationship between neckline and lower opening, but does not reveal the rear edge or fastenings. It cannot confirm a particular backless construction, internal support or fibre. Use the image for its visible front shape and request the missing views from the provider of any actual garment.
If this narrow line interests you, try normal walking and sitting in a similar dress with your planned shoes. Check the leg opening from the side as well as the front. Then compare the straps and upper edge with the underlayers you intend to wear. A long bag strap may cross several of these areas, so test its real position instead of holding a bag beside the dress only. This creates separate answers about front coverage, upper fit and carrying arrangements. The back remains an explicit product question until the actual model is shown from behind.
