Zara Phillips

I don't have a stylist, and I do most of my shopping online, just because it's easier. I don't have any nails to manicure, and it takes me 30 minutes to get ready for a night out, as long as I've decided what to wear first.

My mother is massively into sailing, so we always had Musto clothes, and it went on from there, really. I wouldn't say it's a career in fashion. The range is all day-to-day stuff that I'd put on and use myself.
