We're used to seeing Beyonce flaunting her curves in glittering mini dresses or teeny-tiny hotpants, but it was a very different Ms Knowles seen out and about in Nice over the weekend.
The diva was snapped arriving at Nice Cote d'Azur airport in this monochrome ensemble of skinny trousers, white boxy blazer, retro sunglasses and matching black trilby hat.
Towering peep-toe heels were her footwear of choice, while a pop of colour came courtesy of her matching scarlet fingernails and toenails.
What do you think of Bey's monochrome makeover: is it hot, or not?
She's come a long way - click on our gallery below to look back at Beyonce's dramatic style evolution:
Style Evolution - Beyonce
From a 17-year-old girl group singer to a 27-year-old superstar, Beyoncé Knowles's career and fashion sense have exploded. With her third solo album I am...Sasha Fierce hitting stories late last year, StyleList took a look back at the star's not always stylish evolution.
Sasha Fierce herself recently rocked out at AOL Sessions, !
Can you find Beyoncé in this picture? B - second from right - has come a long way from this sari-clad stop at the 1998 Soul Train awards with the members of Destiny's Child.
At the 1999 Soul Train Awards, the girls of Destiny's Child were a purple haze of taffeta.
Don't blame Beyoncé for the group's third straight matchy matchy trip to the 2000 Soul Train Awards. Blame her mum. Until recently, Tina Knowles was responsible for all of her daughter's red carpet...um...moments. (Maybe that's why the Soul Train Awards went kaput.)
The DC ladies rocked in warrior princess-meets-biker-chick ensembles to the 2000 MTV VMAs.
Making waves? Working the red carpet the 9th Annual MTV Movie Awards in 2000 Beyoncé coordinated the crimping pattern in her hair to the wavy pattern in her dress.
The 43rd Annual Grammy Awards in 2001 were clearly a high point in Beyoncé's early career. Sadly the same can't be said for her fashion choice.
Don't tell mama. Perhaps in an attempt to bond with their young audience, Beyoncé, Kelly and Michelle dressed as Girl Scouts for Nickelodeon's 14th Annual Kid's Choice in 2001.
Fans turned up to meet Destiny's Child while they were promoting their mega hit "Survivor" in 2001. Instead, they were greeted by technicolor cowgirls.
At least she had the good sense to avoid a major J-Lo underwear snafu by wearing pasties under her sheer genie suit at the 2002 Grammy Awards.
