Italian style for me is to have a sense of tradition, respect for one's roots, and a sartorial approach.

I firmly believe in the value of books: it's the way to pass on our work, and it allows us to explore new ways to express our creativity. In this specific case, Mariano Vivanco shot some images of David for this project's purpose.

Both Italy and Britain have a great tailoring tradition. British men are famously elegant and careful with their style: they love to have their clothes tailored, and they often have a trusted tailor who is passed on from father to son. Plus you have this great textile and fabric tradition, which has been a source of inspiration to us.

Do I make fashion mistakes? Yes, but I won't say what.

It's a mistake to think things are as bad everywhere, because in Japan and China there is more cash than in the States. They are full of liquid assets. The big problem is that all the world wants to copy the American system.

My summer time tip is to wear shorts and light shirts; everything in summery fabrics such as linen and cotton. And don't think about work.

The worst times can be the best if you think with positive energy.
