Dating Profile Photo — Side-by-Side Results
Prompt
"A candid dating-profile style selfie of an attractive, approachable woman (mid-20s), shoulder-length wavy dark brown hair, minimal makeup, wearing a light-wash denim jacket over a simple white tee and high-waisted black jeans, warm genuine smile while looking slightly above the phone camera. She’s standing on a sunny city street near a corner café with a takeaway coffee in hand, pedestrians softly blurred behind her, golden-hour natural lighting and a flattering arm’s-length phone angle like a real Instagram story. Keep it casual and authentic—tiny flyaway hairs, natural skin texture, no studio lighting or editorial posing."

- Style transfer can help match popular dating-photo aesthetics (natural daylight, soft flash, lifestyle candid) while staying cohesive
- Face-swap support for controlled identity consistency (best used carefully to avoid uncanny results)
Seedream 4.5 Strengths
- High-quality output with strong general-purpose editing—good for quickly generating attractive, polished dating portraits
