as a hairdresser for over 42+years I suggest ‘when older, shorter is better and more stylish’ but hell I'm just an old lady saying that...
And easier to care for. I'm 65, and have worn my hair short for many years. I hadn't thought of her going for the Hillary look until you mentioned it, but you could be right. Sadly, it doesn't work for either of them. It only makes them look worse than they already are.
