Otome game CG illustration, extremely gorgeous and luxurious. A couple dancing underwater within beams of light in deep-sea ruins, wearing exquisite "Mermaid Concept Haute Couture" (not real mermaids). Male Lead (Deep Sea Prince Costume): He does not have a real fishtail; instead, he wears a pair of exquisitely designed deep blue scale-patterned trousers. The trouser legs feature a special cut that flares out below the knees into a massive, metallic bionic fin-like hem, swaying with the water current like a real caudal fin. The upper body features a translucent deep-sea silk shirt embroidered with ancient wave totems in silver thread, adorned with a magnificent epaulette and chains crafted from black pearls and deep-sea silver. Female Lead (Mermaid Princess Costume): She wears a breathtaking pearlescent gradient mermaid gown. The dress is covered in thousands of hand-sewn iridescent sequins and Swarovski crystals, simulating a gradient fish-scale effect from pale pink to gold, shimmering brilliantly under the light. The massive skirt is the focal point of the design, composed of countless layers of ultra-lightweight tulle, lace, and silk; when spreading out in the water, its diameter exceeds two meters, looking like a giant flower blooming in the deep sea. The upper body is a corset embellished with pearls, shells, and gemstones, with several flowing transparent ribbons wrapped around her arms. Divine light shining, garments refracting light, bubbles, glowing jellyfish. Dreamy, fashion editorial feel, garment details, character close-ups, facial expression close-ups. 8k resolution.
