We’ve all dreamed of taking a walk in our style icon’s glamorous shoes. And who hasn’t channeled their fashion idol before, or borrowed a note from their style book? But, outside of Halloween, few of us get to dress the part, head to toe.

So its no surprise that stylish stars like Katie Holmes, Nicole Kidman, and Allison Williams, jumped at the chance to play some of fashions most famous faces, whether for magazines or movies.

This wave of sartorial nostalgia sweeping through Hollywood has inspired our latest Fashion Flashback: We’re taking a look at all the lucky leading ladies who’ve gotten to dress up as some of fashion’s most iconic women.

Let’s start with the ultimate dress-up fantasies: Holmes scored the role of a fashionista’s lifetime when she played Jackie Kennedy in the TV miniseries The Kennedys, and French actress Audrey Tautou caused major Chanel-envy when she was cast as the legendary designer Coco Chanel in the film Coco Before Chanel.

Then there were the stars who got to play their own fashion idols…

Sienna Miller chopped her boho waves and switched up her style to play her fashion icon Edie Sedgwick in Factory Girl, and Lindsay Lohan didn’t hesitate to throw on a black wig (and lot’s of jewels) to play her idol Elizabeth Taylor in Lifetime’s Liz and Dick.

Playing the part of fashion royalty, Aussie besties Nicole Kidman and Naomi Watts have both transformed into posh princesses of the past for upcoming roles. A style icon herself, Kidman was an easy choice to play actress-turned-princess Grace Kelly, while it’s eerie how much Watts resembled the late Princess Diana while filming scenes for an upcoming movie on the Princess of Wales.

Even fashion icon-in-training Williams has gotten a chance to play dress up in a fashion legend’s closet. The Girls star channeled Catherine Deneuve’s sultry sophistication for the most recent issue of Page Six Magazine.

Check out more stars who’ve dressed the part of fashion’s most iconic faces in our gallery.

The fashion world must be bursting at the seams.

Karl Lagerfeld has just unveiled a series of Victoria Beckham photos he shot for French Elle – and the former Spice Girl isn’t just posing in any regular old room.

The photo spread shows the 38-year-old Beckham — and her gorgeous gams — posing on the iconic staircase of designer Coco Chanel’s 31 Rue Cambon apartment in Paris.

“First pictures from my @ELLEfrance cover shoot with Karl Lagerfeld, a dream come true! X VB,” Posh wrote on Twitter on Tuesday, along with a photo of herself and the current Chanel designer.

Beckham first hinted at the ‘Elle’ photo shoot in July, with personal behind-the-scenes snaps.

On July 23, the mother-of-four revealed the location of her photo shoot to her 4.7 million Twitter followers.
