The wedding dress tiara forms several taller pale points above the hair. A pale veil falls at the sides and behind the shoulders. The dress has an open shoulder line with folded short side sections, a shaped front centre and a broad strongly reflective-looking skirt. A fine necklace descends to a lower central detail. Hands rest beside the skirt area while its complete lower finish is outside the frame. The upper outline is distinct without identifying the materials or fastening of the head jewellery. It offers a height comparison rather than a universal size for another outfit.
Try your actual taller piece with the dress first and compare a narrower headband with the same hairstyle. Look from the front and slightly sideways. Choose the real veil’s distance from the points next and have both connections shown. Add your own necklace after that comparison. The bare shoulders and tall tiara are one possible arrangement, not a general scale rule. Later veil removal needs a trial with your actual pieces so you also assess the hair and head jewellery remaining afterwards.
