Fashion Photography — Side-by-Side Results
Prompt
"A 20s woman with shoulder-length wavy dark hair, minimal makeup, wearing a loose gray hoodie, black leggings, and white sneakers, holds her phone up for a quick mirror selfie while glancing near the camera mid-laugh. She’s in a slightly messy bedroom with an unmade bed and clothes on a chair, soft morning window light spilling in and a casual “outfit check” vibe like an Instagram story. Shot on a phone camera with natural lighting, slight motion blur and imperfect framing for an authentic, everyday UGC feel."
