anvx01,platinum hair, A woman sitting on indoor modern staircase, taking a mirror selfie with her smartphone held in her right hand at chest level, her head slightly tilted down while looking at the phone screen with a soft seductive expression. She is positioned sideways on the step: her left hand placed flat on the step beside her hip for support, her left leg bent and resting on the step she is sitting on, and her right leg extended downward to the lower step with the heel firmly placed on the stair and toes pointing slightly forward. Her torso is upright with a subtle arch in the lower back, shoulders relaxed, body angled slightly toward the mirror.She is wearing a fitted black spaghetti-strap mini dress with a deep neckline, the fabric smooth and hugging the body, paired with black open-toe high heel sandals with thin ankle straps and stiletto heels. Minimal jewelry, elegant evening styling.The environment is a modern indoor staircase with warm LED strip lighting under each step, beige/light cream stairs, a glass railing on the right side with metal framing, and a clean minimalist interior. The mirror captures her full body centered in the frame, vertical composition.Lighting is warm ambient LED lighting coming from beneath each stair tread, creating soft upward glow on her legs and body, gentle shadows, cozy golden tone throughout. The vibe is intimate, slightly glamorous but still casual.(best quality, realism:1.2), raw photo, natural imperfect skin, seductive look, shot on iPhone, grainy, noise, amateur photography, instagram story style
