Many small silver-looking reflections occupy the long dress’s bodice and hip areas. Narrow straps frame a curved upper border with a central indentation. Vertical lines remain distinguishable across the bodice; the shape follows more closely below before widening farther down. A longer rear area rests across the floor to one side. Both hands sit at the hips with elbows pointing outwards. The upper head is cropped.
The more evenly distributed small reflections offer a visible counterpoint to larger floral forms in other references. They confirm neither metal nor a particular decoration type. A closer line proves no age, earlier use or period-specific processing either. Keep those outstanding properties separate from a preference for a long narrower form.
Add a relaxed-arm view on your real candidate where condition permits fitting. Compare hip direction without the arranged hand position afterwards. Your shoes and corresponding back complete assessment of the lower line. Any desired alteration to a genuinely old garment needs independent discussion on that existing piece.
