I think Meryl Streep always looks amazing, she has such great skin, and always has such a lovely smile, and looks so happy. Also, Sally Field, Susan Sarandon, Helen Mirren all look fabulous. And, for the younger ones, Julia Roberts, and Jennifer Aniston have both grown into their looks as they get older. They don't look plastic, and fake, like so many celebrities seem to. As for men, I think definitely Martin Kemp, and also Robert Downey Jr, Pierce Brosnan, Colin Farrell and Brad Pitt, are all improving with age!
