A photorealistic full-body portrait of a 28-year-old Japanese woman with long black hair, standing in a shower. She is wearing a blue T-shirt and silver panties, both items are soaking wet, clinging to her skin, darkened by water saturation, and showing heavy wet folds and glossy specular reflections. Water is cascading down her body, creating a realistic wet sheen on her skin and hair. She has a cheerful expression on her face. The scene is set inside a tiled shower environment. Full body composition capturing the subject from head to feet, high-detail photographic style, sharp focus, natural lighting reflecting off wet surfaces.
