I can make 10 jackets of the same colour, same two pockets and same length, that will look like 10 completely different jackets when you put them on. It's about the way they are cut - it makes them look and feel completely different and move differently, and that's a never-ending study. People who wear my clothes will know exactly what I mean.

This was 1978, when flying was still an occasion, a special grand event that took planning and care. I worked as a TWA flight attendant then. I stood in my Ralph Lauren uniform at the boarding door and smiled at the passengers through lips coated with lipstick that perfectly matched the stripe on my jacket. Mostly, the passengers smiled back.

Go out there and try on everything - short skirts, long skirts, mid length, little jackets, men's clothing - and really look at yourself; really walk around in the clothes. Don't just take someone else's advice. You must feel you in these clothes and feel what it's like to live in them.

My favourite leather jackets are timeless.

I wouldn't buy a book simply because I like the cover. I would pick it up. The jacket can call your attention to it. But in that sense, Oprah Winfrey is worth all the jackets in the world. A jacket is basically trying to do what she does all on her own.

Ever since I knew Dad did pentathlon, I wanted to do it as well. I have seen all his old photos, and he still has his Olympic riding jacket, and that makes this even more special.
