Young woman with black bun in white off-shoulder knit AI Image Prompt

A young woman aged 20-26 with long black hair tied up in a fluffy bun, a few strands naturally falling beside her cheeks. She wears a white off-shoulder long-sleeved knit top with a single shoulder strap and unique cutout design at the neckline, fabric soft and form-fitting. She adorns silver teardrop earrings, and her right ring finger features colorful glittering nail art with rhinestones. Her right hand is raised near her face, fingers lightly touching near her cheek, posing elegantly. The background is a solid light gray wall with soft natural lighting from the side or slightly front, creating smooth light-shadow transitions on the face. The overall atmosphere is fresh, sweet, clean, and fair, evoking a gentle and refined fashion sense and a fresh sweet visual experience.
