The duchess stepped out for an engagement during the first week of October, with a new subtle hair change. She added a long, layered curtain fringe to her golden highlights, creating a face-framing definition for a pretty autumnal switch-up. Similar to Princess Diana, Kate prefers subtle changes to her hair so she doesn't take the attention away from the work she is doing. And possibly also because she doesn't want to commit to such a dramatic hairstyle change.
