What's your earliest London memory?
I came with my mother when I was 14 for a girly trip. I remember thinking how nice the taxi drivers were and how well they knew the city, unlike in New York where you get verbally abused wherever you go.
What advice would you give a tourist?
Hit the important museums around South Kensington. The last time I was in London I went to see the V&A's hat exhibition, which was an anthology by Stephen Jones, and it was amazing. Also don't miss Portobello Road and Westbourne Road - you can find little treasures in the market but there are also great stores such as Joseph and Smythson.
