"I have a theory that I call the "Just One Principle". Simply put, when someone modifies an image, they never change "just one thing". Since the artist at Victoria's Secret erased the handbag, they must have changed something else. What else was modified?"in reference to:
"Although the dress appears to have a random noise pattern, there is actually one area where there is a well-defined pattern: her chest. Between her breast the dots form a well-organized "stretch" pattern. The modification also appears in a demosaic analysis as a diamond-shape distortion in the middle of her chest, and in the 2nd principal component as a minor color variation. Digital enhancements usually appear in multiple image analysis tests, and this appears in min/max, PCA, and demosaic analysis, among other tests."
