Actually, most senior women in politics aren't made up to the nines, and do have natural grey hair. Natural nails, neatly filed wouldn't receive comment anything like as much as patterned gel jobs.
Conversely, odd as it sounds, politics is actually one area where I think we prefer women to look their age. Even Margaret Thatcher, though, yes she clearly had 'done' hair (who remembers that it never moved in the wind) looked her age, appeared to have a wardrobe of the same, interchangeable blue blouse/skirt/jacket combo.
it draws more comment if they DO have gel nails or look over 'done'. Theresa May, for example, had grey hair which certainly wasn't wind resistant, or looked like she spent hours weekly in the hairdressers, but what people commented on were her gel nails.
We expect neat and clean in our female politicians, most of whom at senior level are older.
Yes, tights without ladders, but that's no different to trousers without creases, (Boris Johnson, plenty of people commented on his creased appearance and hair that looked like he'd been in a wind tunnel).
Politicians really aren't the best example.
