What’s the last piece of clothing you bought?
A fringed black leather jacket from IRO.
What are you addicted to buying?
You can’t have too many shoes or handbags, though I do try to control myself.
Best ever bargain?
A gorgeous vintage Hermès Panama hat. I found it in a tiny little shop in Saint-Germain-des-Pres in Paris. I bought a lot of items in the store so as a thank you they gave it to me for next to nothing.
Who has great style?
The pages of French Vogue. Emmanuelle Alt’s styling is on point.
Name your favourite high street shop.
I like Zara because the clothes and accessories are stylish and good quality at a bargain price. They’re always up to date with trends.
Any fashion disasters you’d care to tell us about?
Fingers crossed, so far so good. I’ve got nothing to report I don’t think.
What’s your favourite item in your wardrobe?
A Chanel caviar leather boy bag.
