Spiegelselfie-Porträt im Spitzenkleid

Mirror selfie of [Billie Eilish], closely inheriting core facial geometry from the reference photo with enhanced, sculpted cheekbones and jawline definition. Clear porcelain skin showing micro-pores, undereye brightness, and high-gloss long brunette hair with silky texture and strand separation. Outfit: Fitted [off-white floral-lace gown] featuring long sleeves with delicate eyelash-lace cuffs, a modest square neckline, and an elegant structured bodice layered over a matching opaque lining. Pose & Composition: Holding a [pink smartphone] with the right hand to take a mirror selfie, head tilted slightly downward with the face partially covered by the phone. Left hand resting flat near the collarbone with realistic finger articulation. Setting & Lighting: Indoor staircase area with a light beige brick wall, dark wood handrail, and white vertical balusters. Soft indoor ambient lighting with neutral white balance, fine ambient occlusion in the lace fabric, and crisp shadows cast on the wall. Camera Style: Realistic mobile phone camera capture, 35mm lens perspective, f/5.6 depth of field, sharp focus across textures, and subtle authentic digital sensor grain.
