Summer Seaside Blue Jacket Fashion Portrait

Vertical 2:3 medium close-up fashion portrait focused from bust to head. A mature, natural Japanese woman is standing on a sunny beach, positioned slightly left of center with [Profile in blue] aesthetic. Her head is tilted slightly forward, profile turned to the right with eyes cast downward and lips slightly parted in a calm, composed expression. She has clear porcelain skin, coral lips, delicate eyeliner, and a dark brown, almost black [blunt bob] that leaves her neck exposed, with hair strands blowing lightly to the right in the sea breeze. She wears an ivory white V-neck ribbed dress with thin straps and an elegant neckline, paired with a vivid [blue] light jacket slipped off the shoulders and resting above her elbows, exposing her bare shoulders and collarbones. Upper body is slightly angled left. She accessorizes with delicate gold chain drop earrings with tiny transparent stones and a minimalist single-stone necklace. Background features a deep blue sea stretching to the horizon, clear sky, a distant blurred silhouette of an island to the far left, and a white seaside railing below. Strong midday natural sunlight from the upper-left casts crisp highlights on her hair, left shoulder, collarbone, and cheek, with subtle blue fill light on the shadow side and fine sparkling reflections across the ocean. High-end summer fashion photography style, shot on an 85mm telephoto lens at eye level with shallow depth of field, natural skin texture, distinct fabric weave, crisp color contrast between cobalt blue and white, and fine film grain.
