On the December cover of W magazine, Demi Moore's left hip doesn't line up with the rest of her leg. (look right above the 'R' in Moore.) It would seem that a photo editor must have screwed up. According to jezebel.com:
Although W has a history of using master retoucher Pascal Dangin for its celebrity covers and fashion editorials, the magazine's rep says that the retouching was done in-house by Alas and Piggott's staff. We contacted Demi's rep, too, but haven't heard back.
