The two things, love and snow, that make the world look fresh again

The big challenge is a suit not worn with a tie. To me, it's a very odd look. David Cameron and many of our British politicians have adopted this look. I think it is challenging for men to look chic in casual clothing. Most people just want to wear T-shirts and baggy shorts and don't really care, whereas in the old days people used to really dress well in their leisure time. The suit has become a victim of that. day to dress in an appropriate way.

My ambition is to one day shed my wardrobe and figure out how to look like Gilles Bensimon - or a famous stylist - who travels with a Birkin bag and minimal accoutrement and somehow looks cool.

On the plane the other day, there was man who was wearing a tank top, shorts and Birkenstocks - and I don't think that's acceptable. First class should have a f - ing dress code. It's not about money. It's about education. When you build an environment where people can study well, they'll work better. If you teach people to dress correctly, to take personal hygiene seriously, when we teach them about culture, they will be greater.

People tend to wear a suit without a tie but it's a strange look, there's something missing. Either you wear a blazer and slacks, or you wear a suit and tie. It is challenging today to dress in an appropriate way.

I'm always jealous of people in the fashion business, especially women. I always feel like they look so light and chic. They figure out how to wear the minimal sort of outfit, whether it be the Prada uniform or a T-shirt with perfect-fitting Levi's and Birkenstocks.

When I was younger I always had a dark navy, black tie and everybody would look at me like it was odd, but now it is de rigueur. I'm sure it's my input.
