Well, I think that many of mine have shown up in other people's lists, but here are mine:
1. Audrey Hepburn - so beautiful and elegant. Love her eyes and smile!
2. Angelina Jolie - Her cheekbones are to-die-for, and again, amazing eyes
3. Katharine Hepburn - I think people often forget how beautiful she was because she usually played such strong women, especially in later movies.
4. Lauren Bacall - OMGosh those eyes!
5. Catherine Zeta-Jones - ignoring her appalling taste in men, her face is flawless
6. Kiera Knightley - I love her strong eyebrows and her mouth. She was awesome in Pride & Prejudice
7. Zhang Ziyi - So gorgeous, and I love just about all of her movies!
8. Hedy Lamarr - very sweet and innocent looking. Flawless skin!
9. Sophia Loren - while Hedy is beautiful for her sweetness, Sophia is beautiful for her sensuality and exotic eyes
10. Milla Jovovich and Aishwarya Rai - These two are more honorable mention. For me, they straddle the border between pretty and beautiful. Don't ask me to explain that line, I just know it is there ~LOL~
