For Moss, jeans are a major style statement, not a no-brainer slob-out basic. Often, making the biggest statement means choosing a style no one else is wearing yet (Moss wore her high-waisted Ghost jeans when everyone else was just getting the hang of emulating her low-waisted skinnies - and the denim devotees soon switched over and followed Moss's lead). Last week, Moss was spotted in Balmain's bold zebra-print boot-cut jeans - think on Photograph: Dave M Benett/Getty
Wear your cocktail dress loosely belted; don't brush your hair for the red carpet; wear teenage black kohl eyeliner; hack off hemlines with a pair of scissors; buy vintage clothes and accessories that are already a little beaten up. Moss never looks like she's trying too hard which makes it all look effortless, and cool, and fun, and young, and sexy. Take note, Victoria Beckham Photograph: Chris Jackson/Getty
Other than wearing her own Topshop label, Moss rarely shops on the high street. When she was a skint teenager she would buy second-hand cashmere polo necks, silk 1930s nightgowns and original 1940s tailoring from Portobello market. Real vintage clothes can still offer a quality of fabric and cut that no longer exists, and at a fraction of modern designer price tags Photograph: Rex Features
If there's one sneaky style trick that always guarantees Moss is the centre of attention, it's this: she'll wear the exact opposite of what is expected. From a grey, pared-down knee-length shift dress on the red carpet to tight leather trousers and a tuxedo jacket at the strictly-black-tie Metropolitan Ball in New York, Moss disregards the dress code and yet somehow manages to make everyone else feel like they're the ones who got it wrong Photograph: Yui Mok/Press Association
A cotton shirt in a pale blue cowboy plaid, a foxy ocelot-print jacket, classic stripy tops (thin and French, or wide and punky), 40s-style floral dresses, a glam-rock star pattern blouse ... Moss keeps her prints simple and classic. She rarely wears a designer's print of the season, or unusual or stylised modern patterns. This is the key to her timeless style Photograph: Richard Young/Rex Features
Moss is short (5ft 7in) and very petite, but this is a great tip for flattering and slimming any body shape. Moss regularly has clothes altered that do not fit her signature ribcage-hugging silhouette; it's a simple but subtly effective device and means that the clothes always look as if they were made for her, and could never have been worn by anyone else Photograph: Doug Peters/Empics Entertainment
Hippy, punk ... glam rock ... 1960s ingenue ... 1920s starlet - Moss flits effortlessly between personae without ever looking like she is wearing fancy dress. She pulls it off because she always buys authentic pieces rather than "get the look" styles. Whether it's a genuine 1920s beaded flapper dress, a man's trilby or Hunter Wellington boots, Moss's clothes have integrity, which is why she always looks like the real deal Photograph: Anthony Devlin/Rex Features
For Moss, getting dressed has never been about fashion. It has only ever been about clothes. A beautiful silk blouse is a beautiful silk blouse, so how can you go wrong? A trench coat that fits you to perfection will always look amazing Photograph: Matt Baron/Rex Features
Moss mixes clothes that really shouldn't go together. A lace Victorian mourning cape with PVC jeans? Punk boots with a sequined dress? A prom dress with a leopard-print coat? She breaks the usual style rules and sets off new trends worldwide Photograph: Matt Cardy/Getty
From the 19th-century diamond drop earrings depicting flowers growing in a pot, to the simple set of diamond, sapphire and ruby bangles she was given by Donatella Versace, Moss knows that nothing brightens up a simple outfit like some serious, but subtle bling Photograph: Remy de la Mauviniere/AP
