Certainly Princess Letizia of Spain, She is so much beautiful, has perfect face and eyes. A woman like her nearly 40 and even with less makeup, jewels and professional help in style, still look perfectly good in her face. Her face is the centre of focus when looking at her which should be considered as BEST-LOOKING. I have seen a lot of pictures of other royals ladies, they are good-looking when haveing heavy makeup, pretty jewels and with brand name clothes but when without those assisting tools, they totally looked like other person, just a normal woman on the street. I will say they are both good-looking but when lookign at them, the centre of focus always not towards to her face and body but the clothes or jewels or maybe some accesseries.
