I just saw the New York Times article and was pretty sure it was being discussed here.
I don't like the idea that having long hair is seen as a "mark of feminism." WTH? Isn't feminism about choice?
I still say that many older women are kidding themselves that long hair is flattering on them. Look in the mirror. Consider your face shape and the size of your features, your eyes in particular. Long hair can swallow up small features and/or drag down a long, angular face. It just doesn't work on everyone. There is nothing attractive about a hairstyle that screams, "Get this woman some coffee and a facelift!"
I have to say that I'm glad that Hillary Clinton let her hair get a little longer, just because the length softens her round face. On the other hand, I don't think BSL hair would suit her or be appropriate for her age or profession.
