Well, I could do it for a day, but I wouldn't want to be a teenager again. I really wouldn't.

I don't have great thighs. I have very big breasts and a soft, fatty little tummy. And I've got back fat. People assume that I'm walking around in little spaghetti-strap dresses. It's insidious - Glam Jamie, the Perfect Jamie, the great figure, blah, blah, blah. And I don't want the unsuspecting 40-year-old women of the world to think that I've got it going on. It's such a fraud. And I'm the one perpetuating it.

Now all of a sudden I'm so less interested in pretending to be a lot of other people, and much more interested in being me.

Pick clothes that you really love. And wear them. And don't make anything "special." If it's being held for something "special," wear it to the market. Wear it every day!

I was doing a children's book on self-esteem, and I really felt like I wanted to shed the shame I'd been feeling - and maybe make it easier for women my age who had probably felt bad about themselves.

The same way that mid century modern architecture was in the 50s, I want to be as a human being. New. Different. Challenging the old. Function over frivolity. Clean living. Clean lines.

If you just watch a teenager, you see a lot of uncertainty.
