A portrait of a captivating and enigmatic girl with long, flowing silver hair styled with a single, large braid adorned with a silver ribbon. Her piercing blue eyes convey a sense of both intelligence and vulnerability. She is wearing a flowing, elegant dress with intricate lace detailing, and a subtle smile plays on her lips. The background should be a soft, ethereal gradient of pastel colors, creating a dreamy and whimsical atmosphere. The overall style should be a blend of anime and realistic, with a focus on capturing her delicate beauty and alluring aura.
