The title of her first big feature film pretty much sums up Jennifer Aniston's red-carpet approach: <em>Picture Perfect.</em> The American actress, 51, was one of the pioneers of the ultra-polished look that swept through Hollywood in the early '00s, with her silk bias-cut dresses, sleek hair and pared-back make-up. However, when the star first burst on to the scene in 1994 sitcom <em>Friends</em>, she wasn't immune to the denim waistcoats and voluminous tailoring of the decade. However, as her star rose, so, too, did her styling budget, with Aniston developing a penchant for classic A-list labels, including Valentino, Versace and Prada. While a long-time friend of the timeless LBD, the <em>Marley & Me</em> actress has also dabbled with pops of colour and scene-stealing sequins in recent years, though always coming back to her minimal signature style. Here, we take a look at how the star's style has evolved throughout her time in the spotlight. <strong>Scroll through the gallery above to see more images of Jennifer Aniston through the years.</strong>
