The open wedding dress back forms a deep V here. Floral leaf-like edges accompany the opening. Three curved reflective bead-like strands run from the shoulder areas across the back, with another route at the neck. Only a smaller decorated part of the skirt remains visible. The photograph therefore suits a comparison of back lines in particular. Reflections establish neither real pearls nor LEDs, and this view supplies no complete technical description of the elements.
Consider the spaces between the strands and open back surface first. Would you keep those additional lines or choose a quieter contour? Compare the same area on the real model, adding your planned hairstyle if useful. The close view answers the jewellery question better than your preferred skirt width. Request a complete view of the same version for that separate choice.
Clarify afterwards whether the pictured strands belong to the offered dress or are intended as a separate element. Ask about the confirmed fastening and supplied instructions. Derive no removal or care method from the image itself. Both your preferred back drawing and the actual included combination matter for selecting the offer.
