Emily Blunt's Show-Stopping Style Transformation, In Photos

British actor Emily Blunt is probably best known and most loved for her role in "The Devil Wears Prada". The star rose to fame in 2006, when she took on the role of work-obsessed assistant Emily Charlton in the first film. In 2010, she married American actor John Krasinski. After welcoming two children and fostering a healthy work relationship, the pair became an iconic Hollywood couple. In 2026, Blunt spoke to E! News about her husband's reaction to "The Devil Wears Prada 2." "He loves this one," she said. "He's a massive fan of the first movie, so I think everyone was thrilled," she added.

As fashion can often reflect personal transitions, throughout her developing career, Blunt's wardrobe has displayed her growing confidence in the industry. Since she entered the public eye in her early 20s, with one of her first roles being in the 2004 film "My Summer of Love," Blunt has had a notable style evolution. The actor played it safe on red carpets at first, clad in dark colors and simple dresses. After starring in "The Devil Wears Prada," which was set in the office of a top fashion magazine, Blunt experimented with her style choices and appeared at events wearing statement dresses. When she finally cemented her place as a Hollywood star, the actor started to work with major designers such as Michael Kors and Alexander McQueen. In recent years, Blunt has taken red carpets by storm, showing up to events wearing unique gowns and power suits.

In 2004, Emily Blunt starred in "My Summer of Love." The drama was her first film, and her monochrome dress at the British Independent Film Awards that year reflected her newness. As black garments have been associated with being introverted, it's safe to say Blunt may not have been feeling too confident when she turned up to the event in the halterneck number. The actor's midi dress featured a subtle asymmetric hemline and she kept her accessories minimal, adding a single white bracelet. Blunt styled her hair in a side part and finished the look with a pair of bronze flats.

In 2007, at the BAFTAs, Blunt stepped onto the carpet looking like a 1920s flapper girl. The statement dress marked a fashion shift for the actor, who posed in a tiered black and turquoise gown. The maxi number featured a sheer lace fabric and fringe detailing that merged each segment. The fringe edging was adorned with beads that fell loosely. Blunt had clearly been inspired by the dramatic and stylish costumes worn by the cast of "The Devil Wears Prada," considering the film was released only one year prior to the event.

At the Screen Actors Guild Awards in 2009, Blunt exuded confidence in a backless maxi dress. The actor appeared at the event wearing her hair in a slicked-back bun, and while Blunt's natural hair color isn't red like her "Devil Wears Prada" character, it did look slightly auburn at the event. Her metallic gown stood out against the red carpet and suggested she may be stepping out of her comfort zone. In what could have been a bid to draw attention to the dress, she wore few accessories, including a pair of diamanté earrings.

Emily Blunt knew how to ace the sheer dress trend in 2017. Blunt contradicted the stereotypes attached to new mothers when she returned to the red carpet after giving birth to her second daughter in the summer of 2016 wearing a sheer dress. Some women have experienced shifting style identities after giving birth, but it seems for Blunt, becoming a mother for the second time pushed her to experiment even more. The actor showcased her new haircut, opting for a blond straight bob that drew attention to her pink chandelier earrings. The sheer dress featured delicate floral embroidery and a deep V-neck.

At the 'Camp'-themed Met Gala in 2019, Emily Blunt arrived at the event covered in gold sequins – 510,000 sequins to be precise. The actor attended the fundraiser alongside fashion designer Michael Kors. In an interview with People, Blunt's stylist, Jessica Paster, said the actor wanted to have fun with her outfit and intended to go above and beyond. "Emily just tried it on and thought it was so much fun," she said. "Emily and I wanted a great, fun and iconic look. Camp but still Emily," she added. The hand-embroidered dress took 1,500 hours to create and featured 1,344 gold crystals.

Emily Blunt had a full-circle moment when she returned to wearing fringe in 2023. At the UK premiere of "Oppenheimer," the actor wore a sequined Alexander McQueen gown that featured subtle fringe detailing — contrasting with her bold flapper look in 2007. Blunt's look was slick and showed that she had not only found her feet in the acting world, but the fashion industry too. The asymmetric bodice made the tassel skirt appear discreet, and her sweeping fringe mirrored the dress's curved neckline. The shoulder pads created a dramatic edge, very fitting for the premiere of a biographical thriller.

Considering sequins were in for 2024, Blunt cemented herself as fashion-forward when she stepped onto the carpet at the Critics Choice Awards that year wearing a maxi dress adorned with sequins. As one of Blunt's more bodycon numbers, the red dress, by Armani Privé, also portrayed Blunt's growing self-assurance. The actor drew attention to the vibrant red number by wearing red nail varnish and red lipstick, a stark difference from the more natural makeup looks she donned at previous events. The asymmetric shape of the dress, which featured one sleeve, and the large floral appliqué also made a change.

In 2026, Blunt has come a long way from the young women wearing a plain black dress to premieres. The actor made headlines when she stepped out wearing a tiered ball gown at "The Devil Wears Prada 2" premiere in New York. The blush gown, designed by Schiaparelli, featured a layered tutu skirt. Blunt drew attention to the circular neckline by styling her hair in a slicked-back bun and finishing the look with nude heels and a subtle pearl choker. The statement dress was taken from the designer's spring 2026 couture archive and boasted a feathered corset that created a bird-like illusion.

Emily Blunt arrived at the final premiere of "The Devil Wears Prada 2" in London wearing a red pantsuit. Blunt's power suit was a custom look by Balenciaga. The co-ord boasted tailored trousers and a corset bodice that featured a dramatic cape-like train. She finished the look with a pair of red pumps, also by Balenciaga. Despite standing in front of a red background wearing an all-red look, Blunt didn't blend in. In fact, she made headlines for her fashion choices instead. While the actor kept her makeup minimal, she maintained a glamour feel by wearing a Mikimoto pearl choker.
