I wanted the collection for Target to reinterpret all the must-haves of Stella McCartney for winter and to make my designs more accessible to a wider audience in Australia.

I wanted to make a film that was sophisticated and emotional, but for a wider audience.

My fragrance is rose and amber, and I was just very specific. A lot of what I've done, at the stages I've done it, I've been a little naive, which brought with it a kind of charm. I did Stella a while ago. It's now a bit of a classic.

Let it be

I'm obsessed with not chucking away food. I'm lucky enough to have a gardener, so we grow sweetcorn, tomatoes, beetroots, cabbages, pumpkins, lettuce. I'm trying to get into blanching it and freezing so I don't have to buy veg over the winter, but then you need loads of freezers, and that's not ideal.

Everyone can do simple things to make a difference, and every little bit really does count.
