You’ve worked with a lot of hairdressers and make-up artists over the years. What are the best tips you’ve picked up that you still swear by now?

There’s been so many different things, but the thing I notice the most is that make-up is always about skin preparation. So many people don’t realise how important it is, but skin is the canvas for make-up, and even just observing things like that kind of melted into my approach and philosophy as well. I also remember Pat McGrath had this thing where she would rub foundation into the palm of her hands before putting it on, and she would apply it with her hands directly onto the skin. I always thought that was such an interesting approach and it really does make a difference – it kind of creates this almost second-skin-like finish. I think she said it’s something to do with warming the product up first so it almost melts into skin differently. And I mean, she’s Mother, so we listen to anything that she says.

Are you always surprised at how much of an impact your choice of fashion, make-up and nails has on the world?

It is always very surprising to me – usually all the things I’m sharing are just my personal things that I find to be fun. Like, this is just what I do with my nails. Or this is just the way I like to dress, here’s my approach to make-up, to skincare. But I love sharing with people because I find that the beauty community is so fun. We’re all learning from each other and I feel very lucky to be in that space and I feel very embraced by it. The fact that anybody likes what I do is such a blessing; it’s so nice and it’s so fun, because in my head I’m just a girl. Obviously, I know my life is completely different to other people’s, but this is a big part of how I stay true to myself and I like sharing things.
