Probably both age and depression. Getting old is depressing. But it isn't all bad. As you age, makeup that looked good now looks pretty bad. Better to reevaluate what face you want to put out for the public. No amount of makeup will make you look 20 again. Same for clothing. It is why we have the term age appropriate.
Besides, who were you dressing for anyway. You are supposed to dress to make you feel good. If frumpy feels good there is nothing wrong with wearing it. As I get older, there is less and less chance that I will impress some woman enough to jump in bed with me. So, I always go for comfort.
I also admit to not watching much news. The world is filled with idiots and there is nothing that I can do about it.
I have never understood the fascination with high heels. Lol.
