Dress code: Lulu Guinness

What are you wearing right now?

I'm in a Vivienne Westwood black dress, a Moschino cropped cardigan, and some Marni platforms.

Who's your style icon?

Elsa Schiaparelli – her style and designs were very avant-garde for her time, and many of my designs are inspired by her.

What can't you live without?

Red lipstick, heels and handbags.

Describe the best outfit you have ever worn.

The dress I wore to my 20th anniversary party that Giles [Deacon] made for me especially. It has two eyes, so when I was clutching one of my lips-shaped bags it all made a face.

What's in your wardrobe?

Lots of vintage dresses and Moschino pieces, mixed in with a few high-street pieces I have picked up when shopping with my daughters.

What's in your make-up bag?

MAC's Ruby Woo lipstick – a bright scarlet shade that I wear constantly.

If you could live in any decade, style-wise which would it be?

The Fifties. Most of my clothes are from or inspired by the Fifties shape and silhouette – tea dresses with small waists, that sort of thing. I just love the glamour of that era.

How often do you look in the mirror?

Only when applying my lipstick.

Any fashion confessions you want to share with us?

Spanx pants...

What's your secret style tip?

Always make sure you feel happy in what you are wearing, and then it shows.
