The cat's out of the bag: mystery solved. It's a shame I didn't do Nao's bag as a contest ('the wonderful world of nao'), as you've guessed correctly! In Nao's own words:
the bag is by LONGCHAMP as everyone says!
they know well!!
it was Longchamp x Charles Anastase (LFW catwalk designer, link here) limited edition bag.
i love his collection!!
i bought this in Dec last year, so the longchamp shop in bond street might still have some.
There was another pattern with ballet shoes on, but i liked catty one more!
(me again). Can you see - I hope I"ve made it large enough - he's even put slightly different colours in the whiskers! Love it.
When I met & shot Nao the first time - in the press room - it was crowded, and the lens I had that day meant I had to back up to get her all in. So I asked her to stand on the couch. But first, she didn't want to ruin it with her shoes, so she put newspapers under her shoes. I'm just saying: that's the kind of thoughtful girl she is.
I love seeing the progression of how people dress from one day to another. As you can see, Nao happens to be wearing the same cardigan on both days, with two different looks, but both, still very much her own voice.
