Fashion Photography — Side-by-Side Results
Prompt
"A 22–28-year-old woman with shoulder-length dark brown hair in a messy claw clip, minimal makeup, wearing a thrifted oversized gray hoodie and straight-leg light-wash jeans, holds her phone slightly above eye level and looks near the camera mid-sentence like a TikTok “outfit check.” Standing by a bright café window with a half-finished iced latte on the table, natural morning light spilling across her face, a little motion blur from her shifting stance, authentic handheld phone-camera feel. Background shows real café clutter (menu board, other patrons softly out of focus), unfiltered, relatable Instagram Stories vibe."
