I started this charity, Fashion for Relief, in 2005, after Hurricane Katrina happened. New Orleans was actually the first place I visited in the United States. It was one of my first big jobs, a shoot for British Elle. It was April 14, 1986.

I don't always wear underwear. When I'm in the heat, especially, I can't wear it. Like, if I'm wearing a flower dress, why do I have to wear underwear?

I’ve been offered jobs by companies that supported apartheid many times in the 25 years of my modeling career, but I have never taken one of them. I have to refuse that money, because I’m not going to work against my people. They’ve suffered enough.

I'm not going to wallow in self-pity and not live my life. There are always going to be some falls in life for everybody, no matter what career you have. You have to roll with the punches and keep going.

Am I bossy? Absolutely. I don't like to lose, and if I'm told 'no', then I find another way to get my 'yes.'

In charity, every little bit works. You can't change the world. You can't do everything. But you sure try to bring awareness and do as much as you can.
