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

I thought Italian Vogue had always been considered the most experimental, avant-garde magazine. If I was going to use the same kind of language and the same kind of photos or images on the web site, it would be a disaster because Vogue has its own world, and it could be a little bit cold, you know? We don't give what you call a service.

I say let Matteo Renzi work. He took over a country that was in disarray, not florid. And not the other way around.

I like to be risky every day, changing minds every day. I'm not reliable at all in my ideas. I can change my ideas three times a day. I change different things, the parts of the content. But I never change the content of who I am. So my challenge every day is to change and to take risks.

You can look up "heart" and get 100,000 voices, but slowly the ones at the end are no longer credible, so there will be a selection in Web sites, too.

Bloggers now have no concept. They are given things; they put them on, take pictures, and then just disappear from sight. Who cares?

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.
