My schedule is like a diary and goes absolutely everywhere with me. It is colour coded to show which days I am doing what and in which country.
I'll stuff any magazine into my bag. Even if it's not a glossy, I'll grab it in the newsagent and have a good read.
I wear my watch everyday. I've had it for 20 years and rarely take it off. It was a present from my business partner Joseph. I usually also wear a gold bangle — nothing too glamorous.
You'll always find a cashmere V neck in my bag, usually from Thomas Pink. I have one in every shade. I'm all about colour, pattern and texture so I'll probably have a big printed silk scarf on me as well.
I take my camera for inspiration. I'm no photographer so it's just a simple digital one. I sketch my ideas out, too, but I do them in pencil.
If I am doing a show then I'll also need a bit of an entourage — my PA, a PR, a make-up artist friend of mine and my business partner. You need a team for any of the big press launches.
