These 11 photos of Helen Mirren at Cannes Film Festival are proof her style has only gotten more daring over the past 20 years

In 2003, Mirren, 77, attended a day party for the film "Calendar Girls," which she co-starred in with Julie Walters and Linda Basset, wearing an orange sundress, pink scarf, and neon pink-and-blue tote bag.

While she should be credited for the bold color of the ensemble, Mirren's look wasn't even a fraction of how daring her more recent outfits have been.

For the 2007 Cannes Film Festival premiere of the movie "Chacun Son Cinema," Mirren graced the red carpet in a flowing, pale-yellow gown with fluttering elbow-grazing sleeves.

Unlike the previous outing four years prior, this ensemble showed that Mirren was up for playing with plunging necklines and silky fabrics, both of which have become styles that she gravitates towards today.

According to a Just Jared report at the time, Mirren's asymmetrical dress was designed by Elie Saab. She paired it with a silky Ferragamo clutch bag, which matched the gown perfectly.

The look was another leap forward in Mirren's daring style evolution.

The lace gown featured long sleeves and was just short enough for Mirren to show off her criss-cross black heels.

This year was also one of the first that Mirren experimented with having a much more dramatic beauty look alongside a daring dress. For the event, she rocked a slicked-back hairstyle and a bold smoky eye.

The faded dress featured a striped pattern throughout, gold embroidery, and colorful bejeweled detailing along the waist.

Mirren paired the glitzy look with a shimmery clutch and a bold red lip.

With this daytime outfit, Mirren proved she didn't have to necessarily be on the red carpet to deliver a memorable look.

The actor topped it all off with a pair of rainbow-patterned ballet flats.

Together, the gold lining, the dramatic sleeves, and the blend of royal-blue velvet and see-through organza fabric made this one of the most regal-looking dresses Mirren has worn to Cannes Film Festival.

The medieval-inspired gown was designed by Elie Saab for the brand's fall 2017 couture line, WWD reported.

With this appearance, Mirren showed that daring style can be both playful and sophisticated.

While attending the screening of "Les Plus Belles Annees D'Une Vie," she paired a sequined Elie Saab gown with her newly dyed soft-pink hair, which was swept into a loose updo, Town & Country reported.

She paired it with coordinating pumps, a gold clutch, and jewelry with emerald detailing. According to Grazia, Mirren's gown, which exuded summery vibes, was a Dolce & Gabbana design.

The length and sleeves of the mirrored silver gown definitely gave off 1970s disco energy.

And Mirren made this ensemble all the more memorable by switching up her usual hairstyle for a waist-length style, which she achieved with long platinum extensions, according to People.

The taffeta blue dress featured two of Mirren's favorite styles: an off-the-shoulder design and a plunging neckline. Another standout feature of the gown, which E! News reported was designed by Del Core, was the wraparound train.

Just like her 2019 Cannes Film Festival outing, the actor took her daring style up a notch by coordinating the color of her gown with her hair, which she kept in a curled updo.

Mirren, who is the face of L'Oreal, also carried a black fan printed with the brand's slogan "#WorthIt."

Speaking to British Vogue ahead of the appearance, Mirren spoke candidly about how it took time for her to be comfortable on the Cannes Film Festival red carpet.

"The very first time I came to Cannes was so intimidating and terrifying and overwhelming," she said. "Now I can kind of laugh at it and enjoy it. I see it as a performance."

What made her more accustomed to the experience was dressing the part "You must have a dress that fits you," she added. Ideally a dress that's comfortable, but that's rather idealistic because so many of these dresses are not comfortable, but they look amazing."
