If we could pick a royal from any time period, I would pick Princess Grace or Fawzia of Iran for their lovely featues and elegance.
Today I would pick Letizia because she comes across as very beautiful despite the fact that her clothes are not striking like Princess Mary's or Queen Rania's. I also like Lalla Meryem and her daughter Soukeina - both are pretty.
I like Queen Rania as well although she would be my pick for the "whole package." I like Rania's clothing, hair, make-up and overall presentation. If I were to judge her by beauty alone I would definately have her on my list but maybe after Letizia and Lalla Soukeina.
