Alexa Chung recommends investing in expensive items of clothing.

The model-turned-TV presenter - whose unique sense of style has seen her voted one of the world's most fashionable women - says it's important to splash out on a few quality pieces as they will never go out of fashion.

"My ultimate style tip is to invest in pieces that will see you through a good few seasons - I definitely think it's worth spending a bit more on clothes you'll wear time and time again."

Although she is into fashion now, Alexa, 27, insists it hasn't always been that way: "When I was younger, I didn't really care that much about clothes, to be honest. I used to live in cowboy boots and denim skirts, and I wore a lot of my brother's clothes! The highlight of my youth was seeing Vivienne Westwood's wedding dress on The Clothes Show. People say I've got geek-chic style, but I don't try to be geeky! I think I look cool. I'm short-sighted, so I have to wear glasses. My style generally is preppy and tomboyish - I never wear anything too sexy."
