Karl Lagerfeld. Steve Jobs. Barack Obama. Mark Zuckerbergโฆthese are but a handful of successful men whoโve attributed a small portion of their success to having a โwork uniformโ.
Although society grants men the luxury of dressing plainly with no questions asked, it hasnโt always been so kind to women in the workforce (just ask any female politician), however, there are theories to suggest it may well be one of the hidden keys to career success. Why? It all comes down to a concept known as โdecision fatigueโ.
With the average person said to make roughly 35,000 choices every day (Which staffer should I hire? Skim or full-fat? Should I bring an umbrella today?) and women facing more pressure than men over appearance-related decisions, itโs thought that eliminating the need to come up with a new outfit every day can allow the brain to prioritise other work-related decisions.
In short, itโs supposed to save your cognitive capacity for creative thinking where it really counts.
Theories around decision fatigue aside, it could well be that the decision (yet another one) to repeat outfits or choose a signature look simply readies you for a day of work, the old โdressing for successโ adage, by creating a daily ritual to mentally enable success.
And itโs not only powerful men whoโve adopted this mindset, with many female founders and celebrities citing the work uniform as a fundamental part of their daily life.
Here, we take a look at 10 famous women whoโve developed their signature work look over the years and exactly why they love it.

Sophie Coppola
The Marie Antoinette director is all for simplifying her wardrobe, so she can get on with work, previously stating that having โa kind of uniform helpsโ.
โThere are a few things I wear all the time โ Acne jeans, the staples that you just know you like and donโt have to think about too much. And then itโs fun to dress up for special occasions,โ she told The Telegraph.
Colour-wise, Coppola relies on classic navy blue.
โMy friend who designs shoes at Louis Vuitton, heโs always laughing at me. โDo you want it in navy blue, Sofia?โ and Iโm like, โUm, yes, I doโ. My memoir will be called: Does This Come in Navy?โ she said.

Arianna Huffington
The founder of Huffington Post and Thrive, Arianna Huffington is one founder who swears by uniform dressing, and has even gone so far as to advocate women to repeat outfits more frequently to save on time and energy. Sheโs so big on it, in fact, that she even writes #repeat whenever she shares a new image of a previously worn outfit on Instagram.
โI think women should deliberately repeat things they love,โ Huffington said at the 2017 Fortuneโs Most Powerful Women Summit.
โMen have a competitive advantage. They donโt have to waste the kind of energy we waste. Feeling that we have to wear something new every time we have a speech, every time we do something importantโฆso, I deliberately use my Instagram to show myself, for example, at the Time 100 dinner, next to [a photo of] my at the White House Correspondents Dinner, wearing the same long gown.โ

Angelina Jolie
While Jolie may have access to all the best outfits high-end designers have to offer, the actress and UNHCR Goodwill Ambassador keeps things straightforward and low-key when her work doesnโt involve the red carpet.
โItโs all the same. When Iโm not doing this, I wear the same pants and same shirt every day. I donโt change,โ she told MTV at the 2011 Cannes Film Festival.
โOn occasion [I wash them] but I have a few of the same things. Itโs like a uniform.โ

Vera Wang
Also a fan of the work uniform, bridal designer Vera Wang relies on a handful of all-black key staples that she puts on high rotation.
โI realised that everybody in the end comes down to a uniform,โ she wrote in her blog Vera Unveiled.
โIn the endโeven as a fashion professional, or fashion insider, someone whoโs looked at fashion for so long, and from so many different anglesโthere is a uniform that works for you. And that uniform can be modified, and it can be changed, and it can be dressed up, dressed down, explored, taken more street, taken more couture, but in the end, itโs an editing process.
โAnd as you become more certain of your own vision, and your own taste and your own style, as you evolve, as a person, not just as a woman, you do end up in a uniform.โ

Facebook COO Sheryl Sandberg has also โleaned inโ to the power of the work uniform, favouring tailored dresses with minimal jewellery and classic looks that have stood the test of time.

Catherine, The Duchess of Cambridge
Arguably our favourite outfit repeater, even Kate Middleton has developed something of a work uniform when it comes to her royal duties. Along with re-wearing many of her outfits, the Duchess sticks to silhouettes that are clean, chic and comfortable.

Diane von Furstenberg
It seems fitting that creator of the iconic wrap dress, an item revered for its potent all-in-one mastery of style, comfort and timelessness, would also create a such a uniform for herself. And while one would naturally think that itโs the wrap dress, for von Furstenberg, itโs actually the tunic dress, or what she calls a โpetite valiseโ.
โThe wrap dress was born out of that idea,โ she told Instyle.
โI wanted something that was easy, that I could wear anywhere, and, you know, it is easy to pack. It doesnโt wrinkle, and it makes it easy to get dressed, so it works like a uniform.โ

Carolina Herrera
Also amongst the ranks of fashion royalty with a penchant for a work uniform, Venezuelan designer Carolina Herrera considers her signature white Oxford shirt her โsecurity blanketโ.
โFashion is supposed to be for the everyday. I have worn the white shirt since I was very young,โ Herrera told Instyle.
She also praised the classic white shirt for its easy day-to-night versatility.
โIt doesnโt always look like a white shirt even though it is. With trouser or a short skirt it can be worn for day and then later with evening jewels and a ball skirt for night. Sometimes I see people wearing sequins for lunch, and I think there is a right time and place for what you are wearing. You must follow that in whatever you wear,โ she said.
![Hilary Clinton](https://api.photon.aremedia.net.au/wp-content/uploads/sites/5/media/79326/hilary-clinton.jpg?resize=682%2C1024)
Hilary Clinton
Always a fan of the power suit, the former US Secretary of State used to step out on numerous important occasions in varying shades of the same tailored pantsuit.
In her book What Happened, a recount of her experiences as the Democratic Partyโs nominee and general election candidate for 2016 presidency of the United States, Clinton wrote in detail about her love for her signature outfit.
โWhen I ran for Senate in 2000 and President in 2008, I basically had a uniform: a simple pantsuit, often black, with a colourful shell underneath,โ she wrote.
โI did this because I like pantsuits. They make me feel professional and ready to go.โ
Along with wearing the same thing as an anti-distraction technique and to minimise time spent โoverthinkingโ, Clinton cited one other major reason for wearing a pantsuit every day: to help her fit in with the male politicians.
โI also thought it would be good to do what male politicians do and wear more or less the same thing every day,โ she wrote.

Keira Knightley
When it comes to Hollywood celebrities, itโs what they wear when theyโre not on set that tells the real story. In the case of Keira Knightley, her off-duty uniform of an oversized bomber with boots and jeans (which sheโs been spotted out wearing many times) shows a woman whoโs clearly at ease with herself.
