Kate Middleton or what she should be called Duchess Catherine in my opinion is one of the most elegant celebrity I can think of. She has an air about her that is regal. Even in jeans and tennis shoes.
I love the casualness of this outfit. Jeans and a blazer will never go out of style.
She is 5'9" and ways 121lbs or in England they would be around 8 stone. They weigh themselves in stones. A stone is 14lbs.
Oh to be blessed with a face, hair, and body like that but she does work out.
