The pale bow shape behind one shoulder complements a complete longer dress view here. Broader decorated shoulder sections lead towards a deep narrow V-line. Curving motifs spread across the bodice and hip area while the lower outline becomes quieter. A fine band marks the waist. Another band line sits at the neck. Longer pale areas reach the floor behind the body. One hand is near the neck and the other rests beside the hip.
Choose what interests you first in this upper combination: the V-line, neckband shape or larger accent behind the shoulder. Record just one as the main preference. You can then see on the real candidate whether the other pieces complement that intended emphasis.
Ask about each offered piece separately. The photograph does not establish whether bow and neckband are separate, removable or included. Add a rear view of the same actual model and a normal arm position. The visible rear outline is a photographic detail rather than promised multiple pieces or confirmation of a personally commissioned bespoke garment.
