I don't like it, because she's doing it for Hallowe'en. If she had done it as an exercise to see how she might age and still look good, then fine, but she associated it with Hallowe'en, which is all about scaring people and ghoulishness and that sort of thing, and so she's associating aging with that, which is a very negative way to view it, I think.
Mind you, I had to google images of her to see what she looks like normally.
