Anime Swimsuit Poster with Retro Beach Graphics

Create a full-body anime-style summer pin-up illustration of character_name, a cheerful young woman standing barefoot in a relaxed contrapposto pose on a warm off-white background. She has short wavy hair_color, large violet eyes, a soft smile, light blush on her cheeks, and a purple star hair clip near her bangs. Add a small navy beret tilted on top of her head with a red ribbon accent. She wears a sporty one-piece swimsuit: primarily deep teal-blue with white trim, coral-red side panels, and a lavender side insert, showing carefully drawn anime anatomy with subtle shoulder, arm, waist, hip, thigh, knee, calf, ankle, and foot definition. Her left hand rests on her hip, her right arm hangs naturally with relaxed fingers, and she wears one coral wrist bangle. Keep proportions elegant and slightly idealized, not chibi, with clean line art, soft cel shading, gentle skin highlights, and polished Japanese anime character illustration quality. Canvas and layout: Vertical poster composition, 2:3 aspect ratio, full body centered with generous margins and feet visible near the bottom. The background is minimalist retro beach graphic design on cream paper. Decorative background elements: Include exactly 15 abstract graphic elements around the character: 1 large turquoise circle in the upper left with horizontal white stripes across its lower half and a dotted turquoise semicircle beneath it; 1 coral quarter-circle block in the upper right; 1 pale purple grid in the upper right; 1 group of four small yellow triangles near the upper right; 1 blue double zigzag line near the upper right; 1 pale purple dotted rectangular cluster at mid-right; 1 thin pale purple outlined circle at mid-left; 1 coral partial ring arc at lower left; 1 set of five thin black diagonal lines below that arc; 1 lower-left pale purple grid; 1 coral dotted diamond cluster above the lower-left grid; 1 turquoise zigzag line over the lower-left grid; 1 small blue dotted cluster below the lower-left grid; 1 large turquoise stylized water patch in the lower right with white wave lines and a turquoise semicircle behind it; 1 large yellow triangle on the right with a nearby coral circle over a blue dotted semicircle and a turquoise zigzag underneath. Text content: In the bottom right, add small printed date text reading date_text above an elegant black cursive signature reading signature_text. Style constraints: bright airy palette, pastel geometric accents, clean manga/anime linework, soft shading, swimsuit fashion illustration, crisp hands and feet, no extra characters, no heavy realism, no watermark beyond the date and signature.
