Center frame: an elegant young woman in a strapless ivory-white couture gown, wearing long white satin opera gloves and a sparkling tiara/crown. She is smiling brightly and triumphantly with BOTH arms raised high in a joyful V-shape. Warm golden tungsten ballroom lighting, soft flattering highlights on skin, realistic fabric texture. Background: a crowded formal event with men in black tuxedos and bowties and guests in eveningwear, softly blurred with shallow depth of field and gentle bokeh. The vibe is celebratory, luxurious, and candid. No text, no logos, no watermark."
