What works with your skin and eyes? Use that to zero in on your wardrobe.

Just like girls need to learn to be comfortable in heels before they go out in them for the first time, a man should try wearing a suit throughout a normal day. I do most things in a suit-and sometimes even in a tuxedo-and so I'm really comfortable in one.

I probably do have an obsessive personality, but striving for perfection has served me well

I'm not designing clothes for someone who is doing lines of coke off the table, like I was when I was at Gucci and Saint Laurent

I never want to retire until the day I drop dead. I want to work and work and work because work, I don't do for money, I do for love. And I love to work.

One of the most important things is to figure out what your look is — I don't wear this black suit-white shirt combination all the time to try and be iconic — but because I'm most comfortable in this. Cary Grant never turned up in a pink jacket and hot pants and I don't feel the need to experiment when I know I like dressing this way.

I'm a perfectionist, to the point of insanity.
