Fashion Photography — Side-by-Side Results
Prompt
"A 20s woman with shoulder-length wavy dark hair in a simple white ribbed tank, light-wash straight-leg jeans, and worn-in sneakers holds her phone at arm’s length for a casual selfie video, glancing near the camera mid-sentence with an easy, approachable expression. She’s standing by the window of a cozy neighborhood café with a half-finished iced latte on the table, warm natural daylight and soft shadows, slightly messy background with other patrons blurred like a real Instagram story. Shot on a phone front camera feel, subtle motion blur and imperfect framing for authentic TikTok/UGC vibes."
