Go to Pinterest and save 1–2 photos with the pose, outfit, and lighting you want.
Upload that photo and ask:
“Describe this image in detail without mentioning the person’s face. Focus on outfit, background, lighting, pose, and camera angle.”
Feel free to tell it not to describe any change you want in your own picture, like outfit color change, tattoos, background, etc.
Copy the final PROMPT ChatGPT gives you.
Use soft light near a window, no filter or makeup.
