I've built my wardrobe color palette around red, so I'm happy with it, but I do get pangs when I see beautiful brunettes. I've already been blue, green, black, and blonde.

Everything has such order and everyone is so focused on doing what they're doing that no one ever pays attention to you spinning and dancing around supermarkets. It's something you find in places like supermarkets and airports, where everything is really ordered. There's something about those places that makes you feel really anonymous.

I'm obsessed with choirs, and always have been, because of that sense of overwhelming vocals.

The aesthetic came along the way, I think - just through experimenting, and going on tour, and trying stuff out on stage, having fun with it, and not taking it too seriously. If I had a ballgown at home, I'd wear it onstage. If I found something in a charity shop, I'd wear it. That's where it grew from - just wanting to play dress-up.

I have this sensation of being in flight all the time, but being on stage is like creating a sanctuary in which you can completely lose yourself. The bits of your personality that you keep under wraps in ordinary life, you can let them run free.

I'm down to bleach my eyebrows again. I tell you what, though - that didn't go down well with my boyfriend. Girls love it. Guys, not so into it.

If you asked me to go back to being 14 or 15, I couldn't - it was a terrifying time. I was so awkward in my own skin. I used to hide behind my hair because I was so ridiculously self-conscious.
