You can't go wrong with Clarins, I have found.
The jeans and blazer and heels look on MM is quite preppy, especially with the hat. I see many trim looking women in this look. I also see this look with the women in very smart flats.
I suspect the jeans signal that she is still on mat leave and that her visit was informal.
The vile comments under that DM link are gobsmacking. There is something very wrong with people who are so consumed with hatred.
