Five things I know about style: Katy B

1 It's healthy to experiment. I went through lots of embarrassing phases when I was younger. I once worked at the Nike shop in Brixton and I'd team up trainers with puffa jackets – I had a gold one I'd wear all the time. 2 Keep it simple and comfortable. I love wearing skinny jeans, a fitted white vest top and a pair of white Vans trainers. I'll wear a box-fresh pair when I want to look slick. For a cooler look, I'll wear a battered pair. 3 Know yourself. There are certain things I can't carry off, so I avoid them. Big earrings aren't really for me, although I like them on other people. I'm quite shy so I don't wear clothes or accessories that are too loud. 4 Good fit makes a huge difference. I'll wear a dress and heels for special occasions and I love it – but it's all about the fit. It makes your figure look better, and that's something I've only learned in recent years. 5 There are two essentials every woman should have in her wardrobe: good shoes and a lovely coat. I love Nicholas Kirkwood shoes. They always sorts me out for shoots so I now have a little collection. Katy B performs at this year's Wireless festival, 1-3 July ( wirelessfestival.co.uk )
