Poster Anime con Costume Retrò

A full-body anime-style summer pin-up illustration of [Oyagi], a cheerful young woman standing barefoot in a relaxed contrapposto pose against a warm cream off-white background. She has short wavy [blonde hair with peach-pink underside tips], large violet eyes, a soft smile, subtle blush, and a purple star hair clip by her bangs. She wears a tilted navy mini-beret with a red ribbon accent and a sporty one-piece swimsuit in deep teal-blue with crisp white trim, coral-red side panels, and lavender inserts. Her left hand rests on her hip, her right arm hangs naturally, and she wears a single coral wrist bangle. Proportions are graceful and idealized with clean manga linework, delicate cel shading, and gentle skin highlights. Composition: Vertical 2:3 poster layout, full body centered with generous margins and feet fully visible. Background elements: Minimalist retro beach graphic design featuring 15 abstract accents: a large turquoise circle with white horizontal stripes and dotted semicircle, coral quarter-circle block, pale purple grids, yellow triangles, blue zigzag lines, dotted clusters, an outlined circle, and a stylized turquoise water splash patch with wave graphics. Text: In the bottom right corner, small printed date text reading "[July 23, 2026]" positioned above an elegant black cursive signature reading "[Oyagi]".
