This is common to me. Everyday I see women 50-60+ wearing clothing that is meant for women much younger. Throw in mascara, rouge, and bright red lipstick and it gets kind of silly. But yes, I see this all the time.
In fact, I was guilty of this myself as I hit the mid-thirties only because I was clueless. My body may have been 35 but my brain didn't realize it. Finally a female friend quietly urged me to drop the jeans and to buy some slacks, kakis, and polo shirts. That was the time I transitioned into a blazer wearing middle-aged man, even with a matching hat sometimes. lol
Go back to Melania Trump and you will find class, dignity, and a woman who dresses for her age.
