Woman in white bikini compares blue top by pool at golden hour

Theme: Early evening on a sun lounger by a hotel pool: she wears a white bikini and holds up a light-blue bikini top to compare the colors, sunglasses pushed up on her head, looking at the camera. Girlfriend-POV, candid amateur-style bikini portrait.
Subject: A clearly adult 24-year-old East Asian woman with a full, balanced figure: a pronounced, naturally rounded upper body with soft natural weight, a clear but not exaggerated bust-to-waist contrast, no implant look, a slim waist, rounded lifted hips, long legs, and realistic torso-to-waist proportions.
Person and Expression: A real-looking portrait, as if taken casually on a phone by her boyfriend: natural, slightly asymmetrical features, normal-sized eyes, a soft natural nose bridge and jawline, visible pores and fine skin texture, light makeup, peach lip color, a slight sunscreen sheen on her skin; long hair in a loose bun; sunglasses pushed up on her head, looking up at the camera with a playful half-smile, as if asking which color suits her better.
Outfit and Pose: A plain cream-white string bikini, with natural cup structure that supports her full bust without pushing it up, and a low-rise side-tie bottom, so her waistline and midriff are fully visible. She sits on a white lounger by the pool leaning toward the camera, waist dipped, legs together and angled to one side. Her right hand (camera-right) holds a light-blue bikini top up at shoulder height, and her left hand rests on the lounger. Elbows never cover the chest; only two arms and two hands in total, five fingers on each hand, natural structure.
Background and Lighting: Hotel poolside with sparkling blue-green water, a glass of lemonade with a straw on the small table beside the lounger, and palm-tree shadows. Low, warm golden evening sun that gives her skin a warm rim light and soft shadows.
Composition and Camera: Vertical 9:16, 35mm, close girlfriend-POV, camera slightly high and angled down, framed from the top of her head to mid-thigh with her face, chest, waistline and the blue bikini fully in frame, focus on the eyes.
Texture and Style: Unedited phone photo look, like a casual portrait-mode shot: natural skin, no heavy retouching, light grain, real skin texture and individual hair strands.
Negative: Avoid a fake smile, avoid a stiff toothy grin, avoid a childlike look, baby face, AI influencer face, oversized eyes, pointed chin, malformed fingers, extra fingers, extra limbs, hyperextended arms, distorted body proportions, face distortion, over-smoothed skin, plastic skin, underexposed image, low quality, blur, text and watermarks
