Dress code: Roksanda Ilincic, designer

What are you wearing right now?

We have 20 centimetres of snow in London, and I am definitely dressed warm: YSL trousers, Roksanda Ilincic blouse, a big vintage jumper, Chanel belt and jewellery.

Who is your style icon?

It is Barbie's 50th birthday this year, and I have been making her a special dress for the occasion – her archive has some of the most glamorous and unexpected outfits in it, and she is definitely my style icon this year.

What can't you live without?

My bright red lipstick.

Describe the best outfit you have ever worn

It is hard to pick one. However, the last outfit that made me feel really special is the long Swarovski cape from my spring/summer 2009 show (pictured far right). I recently wore it to a dinner party!

What's in your wardrobe?

Dresses from my own label, lots of vintage pieces, and plenty of big jewellery.

Make-up bag essentials?

MAC lipstick – at least three colours; Shu Uemura eyelash curler and mascara; YSL Touche Eclat; organic antibacterial handwash; and lots of other products that I never really use.

Most stylish era?

Actually, I am quite happy with the present one – maybe I would fast-forward out of the recession though.

How often do you look in the mirror?

Well, every time I have to put on or reapply my lipstick...

Any fashion confessions you'd like to share with us?

Oh yes, plenty of confessions to make – but I think I'll try to keep them as secrets!
