On duty V off duty celebrity wardrobes

'Tis a rare gift to be able to work an off-duty casual wardrobe as well as an on-duty high fashion and high glamour outfit. So in honour of those who seem to manage this difficult task as easy as breathing air, we run down our fave stars who manage to go from one end of the style spectrum to the other like sartorial magic.
FlynetOff Duty: Lily Allen
Out and about for a stroll in New York and Lily's got a whole luxe urban vibe going on in the wardrobe department.
Rex FeaturesOn Duty: Lily Allen
Fast forward a few hours to a Chanel dinner and the British singer goes girly in a heartbeat with this gorgeous tweed and silk Chanel tea dress.
Rex FeaturesOff Duty: Kristen Stewart
Working mannish tailoring to the max in this charcoal grey cropped trouser suit ensemble, Kristen put her own stamp on the look with a soft grey beanie hat as she darts around New York between interviews.
Rex FeaturesOn Duty: Kristen Stewart
Come the evening though and at the premiere of her new film, Kristen ups the fashion ante in this gorgeous monochromatic Chanel number.

Heading out and about in New York, Victoria Beckham showed she's a pro on the off duty wardrobe front as well when she stepped out of her hotel in skinny jeans and an olive green leather jacket. Being VB, the heels were still vertiginous, though.
WennOn Duty: Victoria Beckham
Wowzer. Pulling out the big guns for a press event at her Dover Street store in London just the following day though and Victoria teamed a killer leaprd print pencil skirt with a chic delicate black knit and simple courts.
Rex FeaturesOff Duty: Suki Waterhouse
Suki's off-duty look is all about comfort and effortless style. Keeping her wardrobe bang-up-to-date with key on-trend pieces like these wide-leg trousers, Suki's model credentials always shine through - even when she's off duty!
Rex FeaturesOn Duty: Suki Waterhouse
Come cocktail hour though and Suki's gorgeous pseudo-90s, kinda grunge runs through to her evening wear too. With the fringe often swept back or to the side for occasions, she can regularly be seen in Burberry dresses - although these heels are Topshop!
x17onlineOff Duty: Kylie Jenner
Wearing the sold out baby blue duster coat from ASOS, Kylie Jenner's off duty look is all about minimalist 90s made glam with statement accessories.
Rex FeaturesOn Duty: Kylie Jenner
Come the red carpet though and Kylie's 90s aesthetic still holds but with added polish thanks to directional beauty looks and killer heels.
Rex FeaturesOff Duty: Kendall Jenner
All black separates with a white tee is the order of the day for off-duty model Kendall.

But fast-forward to nighttime and Kendall's all about the wow factor with her red carpet choices.
Rex FeaturesOff Duty: Hailey Baldwin
Killer ripped jeans are Hailey Baldwin's off duty staple, bar none.
Rex FeaturesOn Duty: Hailey Baldwin
Stepping out in a Reiss jacket for the red carpet, Hailey's on duty looks are all about sharp tailoring with a hint of 90s minimalist thrown in for good measure.
XposureOff Duty: Keira Knightley
Want to channel a bit of Keira Knightley's off duty style? Just grab yourself this cropped star print jumper by Zoe Karssen et voila!
PA PhotosOn Duty: Keira Knightley
But when she's working, Keira's all about the couture, Chanel and immaculate tailoring. Nodding to the 50s in this powder blue poodle-skirted dress, Keira keeps the vintage look bang up-to-date with a halo braid and those punchy silver heels. What a pro.
Rex FeaturesOff Duty: Sarah Jessica Parker
As Carrie Bradshaw, SJP was the style icon for city dressing. While her off-set style is much more relaxed, Sarah Jessica proves she's still got what it takes in the fashion stakes with this sharp off-duty look.
Rex FeaturesOn Duty: Sarah Jessica Parker
But never let it be said that SJP does not make an effort when it comes to her red carpet ensembles. For the New York City Ballet's fashion gala in September 2014, she chose an ornate creation with an exotic twist. See, there's still some of that Carrie magic in there.
Rex FeaturesOff Duty: Poppy Delevingne
Poppy's got an off-duty style that's all her own, drawing on the gritty London street styles looks but tempering them with a laid-back Cali girl vibe, thanks to her years spent in LA.
Rex FeaturesOn Duty: Poppy Delevingne
Come the evening though and Poppy's 100% high fashion, regularly working striking patterns and bold statement tailoring.
Rex FeaturesOff Duty: Jessica Alba
Jessica Alba's chic off-duty outfits seamlessly veer from the boho luxe Cali vibe to sharp and elegant New York street style separates; this look falls firmly in the latter camp and is a canny mix of black, nude and white hues.
Rex FeaturesOn Duty: Jessica Alba
Fast-forward a couple of hours though and J-Alba ramps up the vamp-factor in this gorgeous fuchsia pink fitted shift dress and statement silver courts, nailing that sharp, Upper East Side aesthetic.
Rex FeaturesOff Duty: Kim Kardashian
When the perennially glammed-up Kim Kardashian does off-duty, she likes to work an 'I'm with the band' look, repping her man's tour in a Yeezus T-shirt and obligatory leather jacket and ripped jeans. Note, the sky-high heels are still firmly in situ though!
Rex FeaturesOn Duty: Kim Kardashian
But when Kimmy K does on-duty elegance, chic separates, a killer blow-dry and lots of pencil skirts are the order of the day.
Rex FeaturesOff Duty: Emma Stone
For a trip out and about in her native New York, Emma went for a casual cool vibe in ripped jeans, a sharp coat and those studded Valentino heels.
Rex FeaturesOn Duty: Emma Stone
But just hours later – and never one to shy away from a statement gown on the red carpet - Emma Stone had slipped into this stunning nude Prada number with exposed side and cage detail piping, letting the simplicity do the talking.
Rex FeaturesOff Duty: Emma Watson
Emma Watson's sleek white midi dress is the epitome of chic city dressing, proving that the former Harry Potter star is a wizard at off-duty style.
Getty ImagesOn Duty: Emma Watson
"Oh, what? This old thing. Yeah, it’s cool. It’s just a directional midriff baring ensemble from Balenciaga. Casual."
Although these words never actually left the mouth of Emma Watson, there’s no denying she's got some serious red carpet style up her sleeves.
Splash NewsOff Duty: Beyoncé
How amazing does dressed-down Beyonce look in this monochrome crop top and matching pencil skirt?
Rex FeaturesOn Duty: Beyoncé
But don’t worry about it. If Beyonce’s got some performing to do you can be sure the casual-cool New York street style get-ups are put firmly to the back of the wardrobe and the glitzy leotard costumes are coming out. In short, no one does sexy-glam stage costumes quite like this lady.
Rex FeaturesOff Duty: Kate Moss
Working one of the new season trends – ON A DAY OFF SHOPPING (she really is a heroine amongst women in the fashion department) – Kate Moss’ awesome street style simply knows no bounds.
PA PhotosOn Duty: Kate Moss
Got a big event to go to though and Kate Moss can flick the sartorial switch quicker than you can utter the words, "how the blazes does she do that?".
Rex FeaturesOff Duty: Chloe Sevigny
Oh, Chloe! Thou art painfully cool and make all the fashion trends that shouldn't work, work. Cropped flared jeans, anyone?
PA PhotosOn Duty: Chloe Sevigny
But when the occasion presents itself, Chloe's luxe bohemian style can work for the red carpet, too. Case in point, to your left. (<<<)
PA PhotosOff Duty: Rihanna
Standing under her umbrella-ella-ella (sorry), Rihanna's off-duty style is a styled up sports luxe aesthetic; just check out this oversized basketball jersey, beanie hat and huge hoop earrings.
Rex FeaturesOn Duty: Rihanna
But when she needs to ramp up the glamour for the red carpet, RiRi's no slouch. This canary yellow gown is utterly elegant yet undeniably signature Rihanna.
Rex FeaturesOff Duty: Kirsten Dunst
This is just an off-duty snap of Kirsten Dunst. Yep, this. This amazing outfit just happened when she woke up and put some clothes on.
Getty ImagesOn Duty: Kirsten Dunst
But in another lesson in the eternal masterclass that is How To Dress Well For Every Day Of Your Entire Life by Kirsten Dunst, the On The Road star proves time and time again she can do directional, girly tailoring just as well.
WennOff Duty: Eva Mendes
A rose by any other name... Eva Mendes gets it right - as ever - on a day off in LA in floaty florals with a slouchy tan bag - on a trip to Starbucks, we might add. Yep. She was just grabbing a coffee and looked like this.
Rex FeaturesOn Duty: Eva Mendes
We cannot remember the last time we spied Eva Mendes in trousers and, be it on or off the red carpet, her go-to is always floaty dresses and skirts. However, we just love the way she styles it up for official appearances, often opting for bold prints and sharp high-fashion accessories.
Getty ImagesOff Duty: Rosie Huntington-Whiteley
Rosie's off-duty wardrobe is pretty special, consisting of bold colours and chic separates; enter this silk jumpsuit and the excellent pastel accessories.
Getty ImagesOn Duty: Rosie Huntington-Whiteley
But when occasion calls, the British model can do high fashion with the rest of them - remember this knock-out look from the 2013 BFAs? The colour-block Antonio Berardi suit with slicked back hair is still one of our fave ever red carpet looks.
Rex FeaturesOff Duty: Sienna Miller
Sienna’s off-duty festival inspired wardrobe is second only to Kate Moss’ sartorial prowess on the fields of Worthy Farm. In 2010, Sienna wore this this luxe-boho look like the off-duty style maven that she is.
Getty ImagesOn Duty: Sienna Miller
But we love that Sienna will often hark back to her boho fashion roots on the red carpet, too. This gorgeous emerald green Burberry Prorsum dress epitomises the beauty of her style.
FlynetOff Duty: Alexa Chung
Breathing new life into the 90s favourite - the dungaree, Alexa shows her fashion versatility even when travelling. Just look at that artfully shoulder-robed Burberry trench coat - as you do, at an airport.
Rex FeaturesOn Duty: Alexa Chung
Although she's the queen of off-duty style, Alexa can still do red carpet with the rest of 'em and this Valentino caped mini dress is just a small sample of the mounting evidence.
Rex FeaturesOff Duty: Jessica Alba
Jessica Alba's off-duty style is how we all wished we actually dressed on holiday/the weekend.
PAOn Duty: Jessica Alba
But when it's a high fashion event Jess can switch it up into a ballgown. Easy peasy.
PA PhotosOff Duty: Olivia Palermo
Tracking Olivia Palermo's every outfit is practically a sport but we're more used to seeing the former reality star in sharp, highly stylised outfits at Fashion Week...
Rex FeaturesOn Duty: Olivia Palermo
Indeed, Fashion Week is the prime sartorial stomping ground for Liv – and her signature look of luxe pieces teamed with busy tailored separates is practically her signature these days.
Rex FeaturesOff Duty: Nicole Richie
Nicole Richie's style is all her own and we love to stalk her every look, from those boho maxis to sharper more fashion forward looks like this monochromatic ensemble.
Rex FeaturesOn Duty: Nicole Richie
But the red carpet never flummoxes Richie either. Although her style can divide critics (this Jean Paul Gaultier number split the team a bit), there's no matching her fashion bravado and sense of fashion adventure.
WennOff Duty: Lily Aldridge
Trust Lily Aldridge to get the whole leather trousers thing absolutely spot on. The Victoria’s Secret model gave a master class in how to style them with this simple, loose-fitting denim shirt and super-dooper studded Chloe ankle boots. All at the airport, just by the by.
Rex FeaturesOn Duty: Lily Aldridge
Proving that she's no one-trick fashion pony though, Lily practically took our breath away in this off-the-shoulder gown.
Rex FeaturesOff Duty: Ellie Goulding
Known for her love of super-short shorts, Ellie's off-duty style is fabulous festival-inspired fashion fair.
Rex FeaturesOn Duty: Ellie Goulding
Proving that she’s one helluva style chameleon though, Goulding can change up her look in a heartbeat, but we love that she always keeps it essentially Ellie though with her trademark glossy blonde locks.
Rex FeaturesOff Duty: Fearne Cotton
Fearne Cotton's working wardrobe is pretty much the best collection of clothes we've ever seen. Regularly papped on her way into work at BBC Radio 1, you can always rely on her to have a great coat... and bag ... and sunglasses. Oh darn it, we could go on.
PA PhotosOn Duty: Fearne Cotton
But come the red carpet, Fearne's also a complete glamazon, easily styling high street with high end designer brands, too.
Rex FeaturesOff Duty: Miranda Kerr
Little Miranda Kerr can do wrong when it comes to off-duty dressing. Her look is always classic whilst being bang on-trend, as well. This perfect city chic look is one of our favourites.
Rex FeaturesOn Duty: Miranda Kerr
Like any accomplished style queen though, when duty calls the glamour comes thick and fast with Miranda who'll team her Hollywood hair with a killer dress and heels. So simple, yet oh-so-effective.
Rex FeaturesOff Duty: Justin Theroux
And now over to the men; Justin Theroux is quite the New York street styler, regularly putting together sharp, biker-inspired ensembles to pound the pavements of NYC.
Rex FeaturesOn Duty: Justin Theroux
But come a time when he needs something a little sharper and Justin is all over a chic suit teamed with a skinny tie.
