It’s not aging that is the issue. It’s her determination not to have her hair and makeup done, when she could certainly well afford it. She looks like a fishwife with that dull ratty hair and receding hairline; she does her lips narrowly like she has to make a single lipstick last for several years, and has stopped grooming her eyebrows and lashes. Granted, it’s her choice; but she is a public figure and it wouldn’t kill her to make a little effort, since her clothing is usually very smart. Even her mother at age 93 wears foundation, powder, blusher, a little eyeliner and well-applied lipstick.
I see what you mean. She appears to be very frugal. I saw an article with photos of her wearing the same outfits she wore 20-30 years ago.
On the other hand, she seems comfortable with herself. After all, she has nothing to prove.
But, yes, I agree that she’d look better with a hairstyle and hair color.
