Christine Lagarde, is white haired and her face is wrinkled
Look at all the photographs in that link.
Christine Lagarde sports a perma-tan. She also has (probably) a different disposition to Mrs May. She looks very confident. She exudes confidence . Her clothes are secondary.
I think TM is the workaholic, genuine, honest, no frills woman she has always been.
I also think she dresses to suit her tall, fairly lanky frame. In her slight hunch and flat heels I see a woman who is aware of her towering height, a slightly self-conscious woman who does not want to draw attention to herself. I like it that she is not flamboyant, showy and self-promoting. She just gets on with the job.
I see her as an excellent role model for women in that she is not relying on looks or image to inflate her position. She seems without ego. In these days of flashy, trashy looking, over made up and attention-seeking, superficial women hell-bent on fame, it's a stance to be admired, in my book.
Mrs May got it right, dress wise, on Sunday.
Corbyn was a complete fail, but he knew exactly what he was doing, imo.
