From his interview on wwd.com:

“That said, you’re not a fan of online retail.
I don’t believe in selling luxury online because shopping is pleasant. E-commerce deprives people of the pleasure of shopping in beautiful shops. And you know, fashion is not only what the clothes are made of — it’s the feeling of luxury where you shop, how you shop, the way parcels are beautifully wrapped. (Online) there are too many fakes, too many copies. Originals still have to be seen and touched. Because expensive clothes are not only about the look. It’s also about the touch.

You don’t use Twitter or other social media.
But I have nothing against it. I buy computers because they are beautiful objects. Personally, I don’t use them that much, but I don’t use cell phones and Blackberries and all that. It’s not because I want to be cut off from the world, but because I have different priorities. I like to do everything myself. I know pretty well about dressmaking — a technique that is difficult to get, as you know. My eyes are open, but they are not limited to a screen. For me, the world is a huge screen. That’s how I see it.”
