Appearance is the gateway to one’s personal brand — it is the first thing someone sees, and right or wrong, one of the first things we judge (and are judged on). Just as we grow and change in our romantic partnerships, our family and our career, so too should we evolve within that personal style as we age. Whether Renée Zellweger has had plastic surgery is none of our business; it’s her brand and she can do with it what she wants.
