Hairstyle For Mature Woman With Diamond Shaped Face

I am 68, 150 lbs and have blond hair with light complexion. I have a diamond shaped face, thick hair, but receding some. I would love to see some hairstyles that would suit me and my shaped face. I have tried growing my hair out some, but have never been satisfied. Probably because I did not have a style that was right for me. Any help that you can give me would be greatly appreciated. When I was younger, they said that I looked a lot like Grace Kelly. Maybe this would help you in your selection of hairstyles. As I said, I am very light complected and was very blond growing up. Any tips on makeup ? Hope you can help me. feel that I need to be transformed!!!!!!!!!!!! Thanks for your help.
