Art Deco illustration, stylized digital painting, portrait of a sophisticated woman in 1920s high-fashion attire, wearing a wide-brimmed deep cobalt blue cloche hat adorned with a silver metallic ribbed band and a lavish plume of blue and silver peacock feathers, a single sapphire bead anchoring the plumage, piercing blue eyes, porcelain skin with soft peach blush, sharp contoured cheekbones, deep red matte lips, teardrop sapphire earrings, sleek black finger-wave hair tucked under the brim, wearing a structured metallic blue silk gown with architectural pleating, posing in a three-quarter profile gaze. Composition framed by a massive concentric geometric halo of white and silver stepped tiers, symmetrical Art Deco architectural elements, stylized scrolls and linear patterns in the background. Lighting is a high-contrast studio rig with cool rim lighting and soft frontal fill, creating a luminous glow on the skin and sharp metallic reflections. Color palette consists of royal blue, deep sapphire, sterling silver, creamy white, and warm ivory. Mood is opulent, enigmatic, and aristocratic. Textures of polished satin, brushed chrome, iridescent feathers, and smooth matte skin. Visual style inspired by Tamara de Lempicka and Erté, clean lines, geometric precision, saturated color blocking, cinematic fashion photography, shot on 35mm film, f/5.6 aperture for deep focus across the subject's features.
