I don't like fashionistas. They only wear the brand. You want to become a fashionista? Easy! Spend money.

I feel what is in the air. I go with my instinct.

There are designers there, we have to think of production, but I am not changing Africa. But if we all do something together....We have to know our limits, I don't have the pretense I can change the world. And I don't want to set up events [to raise money]. Because what happens if the following year they don't have an event, they won't eat?

The only time I was really surprised was the reaction to the [shoot dedicated to the] BP oil [spill in 2010]. I didn't expect it at all. It was for the August issue, perhaps one of the less relevant months, but there was so much buzz. It was picked up all over the American television, but I defended my position. I don't understand those that say that a magazine such as Vogue should not talk about these things.

Credibility is a must. Think of all those bloggers that kill us with photos outside the shows - there will be a selection there, too. Not because some are less good, but those that do not impose a style will have fewer requests.

Social media are fundamental to communicate and understand what happens in the world. It's a point of view and an immediate commentary.

I try to renew and create something new every time.
