What kind of photos work best?

Use a single subject, full-body or upper-body, facing the camera or at a slight angle. Good lighting and a relatively uncluttered background help the person segmentation model separate you from the scene. Avoid heavy motion blur, extreme foreshortening, and cropped limbs—the pose estimator needs visible joints (shoulders, hips, knees) to align the garment warp. Mirror selfies work if the reflection is sharp and your outline is unobstructed.
