I am fascinated by the book Looks: Why They Matter More Than You Ever Imagined, by Gordon Patzer. He presents a compendium of research that shows that people do better in life if they are better looking. The research has some predictable stuff, like you get a wider selection of mates, and taller people earn more money than shorter people.
But it's the research about children that shocked me. Mothers give more affection to better looking children. Not on purpose – it just happens. And teachers expect more from better looking children and therefore give more to them.
You can't really change what you were born with – aside from plastic surgery – but you can improve the odds by dressing well.
I want to think I'm above that, but just in case, I splurged for kiddie clothes from Mini Boden.
