Since Brit ‘it’ model Agyness Deyn was featured on a 2007 cover of Vogue USA, alongside a new crop of supermodels including Hilary Rhoda, Chanel Iman, and Lily Donaldson, the style maven’s irreverent and eclectic geek-chic has taken fashionistas the-world-over by storm, spawning a bevy of copycat followers keen to steal her style. And now classic ‘Agyness’ is practically a fashion style in its own right, with the model’s big black eyebrows, her propensity towards little or no make-up, and her trademark messy blond crop with dark roots proudly visible all must-have looks among those in-the-know.

Agyness’ seemlessly thrown-together look is charmingly authentic but utterly unique and totally cool to boot. Her wardrobe staples include working man’s club-style string vests and lumberjack shirts; boyfriend jackets with sleeves pushed up over the elbows; body-con dresses; skinny jeans; trousers that are slightly too short; quirky vintage t-shirts; classic tailored blazers; braces; trilbys; mannish lace-up boots; over-the-knee socks; brogues; and the obligatory pair of uber-cool Ray-ban sunglasses. As a rough style guide to stealing Agyness’s look go for everything slouchy, super-sized and androgynous. Mismatching is key, as is being unafraid to mix it up – think neon with sequins, classic with proper crazy, and 80s with nu-rave. Taking fashion risks is a given.

Currently living in New York and engaged to The Strokes guitarist Albert Hammond Jnr., Agyness has clocked up covers of pretty much every glossy mag worth being on and has even had an entire issue of I-D magazine dedicated to her. What’s more, she’s appeared in ads for Burberry, Giorgio Armani, Mulberry, Paul Smith, Anna Sui and Vivienne Westwood.

And here are a few key style tips for achieving that punk/rock-chick dress-like-we-just-don’t-care Agyness look:

Go for the unexpected – team a slinky body-con dress with mannish brogues or military boots (Dr. Martins) and a pair of over-the-knee socks.

Rock an 80s Agyness style by pairing neon brights with distinctive look-at-me patterns. Topshop, Very and Peacocks are great for bold 80′s patterns and simple loose pieces.

Cropped acid-washed jeans and big baggy tees are just the ticket. Try New Look for on-trend pieces.

To steal Agyness nu-rave style your piece de resistance should be a t-shirt with a super-large slogan.

Agyness celebrates being British whenever she can and can’t resist accessorising with pieces with the British flag on them. An oversized vest festooned with a British flag or a vintage quilted Chanel-style bag with a flag emblem will win big Agyness brownie points.

Mix styles, colours, textures and seasons and, above all, create a look that’s totally yours… well Agyness-inspired yours.

Agyness is big into layering clothes so don’t be afraid to pile it on.

Long necklaces have a starring role to play in Agyness’ accessories.

When it comes to hats, fedoras, knit caps, and hoods are all Agyness approved.

Make-up should be pale, with dark eyes and eyebrows.

Agyness Deyn quotes on fashion and style:

“My mum was always trying to get me into Laura Ashley floral dresses, and I’d be, like, ‘No, Mum.’ But now I love those floral dresses – with a pair of Dr Martens”.

On her fashion icon – the Queen: “I love her Barbour jacket and welly thing when she goes out walking her dogs. Ladylike, but a bit quirky.” She collects royal memorabilia, which she displays next to Sex Pistols souvenirs in her apartment. “Plates, coronation pictures, tea towels and flags. It’s bonkers”.
