IDENTITY PRESERVATION INSTRUCTION:
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while transforming the overall appearance into a 1920s flapper style. The facial identity must remain completely recognizable and true to the original subject.

TRANSFORMATION DESCRIPTION:
Transform the person into a 1920s flapper with authentic Jazz Age styling. Apply a short bobbed hairstyle (finger waves or blunt cut) with a decorative headband featuring feathers or jewels. Style with period-appropriate makeup including dark cupid's bow lips, thin arched eyebrows, and smoky eye shadow. Add flapper fashion elements: beaded dress, pearl necklaces, and drop earrings. The pose should be elegant and confident, typical of the Roaring Twenties era.
