      The blue dress

      1K · 16:9 · MEDIUM

      Original full-body cinematic fashion portrait, horizontal 16:9. Iris, a tall woman aged58, sharply cut silver bob, strong nose, fine eye wrinkles, composed professional expression. A sculptural midnight-blue heavy silk gown with a high asymmetric collar, one plain silver cuff, exactly two simple black heels worn on her feet. Narrow runway end under hard white light; charcoal curtain behind. Photographers stay outside frame. Rich real silk texture, natural mature skin, restrained contrast, poised weight on one leg, no exaggerated beauty retouch. Both shoes and complete dress hem visible. No celebrity likeness, brands, captions, collage or text. This is an identity and wardrobe reference before she leaves the runway. Production language: English for any permitted diegetic writing or visible text. This does not override the request for no typography or text; do not add captions, titles or labels.

      Built-in safeguards and best practices for responsible creation with Nano Banana 2.1.

      • Don’t generate real people or public figures (celebrities, politicians, etc.).

      • Don’t use someone’s likeness without consent.
      • Some prompts and reference images may be blocked — generic characters and scenes are fine.
