Princess Charlene of Monaco and her husband Prince Albert let romance lead the way on Thursday night, attending a candlelit dinner, organised by Monaco City Hall.
The 45-year-old dressed for the occasion, wearing a beautiful navy dress with sheer panels on the shoulders, designed by Swiss fashion house Akris, with fans wowed by her dazzling beauty.
Charlene kept her makeup and accessories lowkey, sweeping her short hair back from her face, allowing the dress to do the talking.
"Very beautiful and elegant," one royal watcher wrote on Instagram, while another commented: "She is very beautiful and elegant Princess Charlene, I wish her much happiness."
A third praised former Olympic swimmer Charlene's toned figure, writing: "With a physique like this, she can even wear a jute bag, she always looks good. She is naturally elegant."
The outfit marks the second time this week that Charlene has gone for a daring ensemble choice, with Monday seeing the royal wear a patent leather strip gown, also by Akris with sheer panels. She wore the slightly risqué dress for a gala dinner, and compliments flooded in on the bold ensemble.
"She looks good, more like her old self again," one fan commented, while another wrote: "The cut of the dress really suits her," with a third saying: "Daring choice and I like that. I think she looks great."
Charlene's sultry dress choices were juxtaposed by the oversized white trouser suit she wore to a dinner with the Mandela Foundation this week. Her varying style choices prove that she can wear just about anything – and always look fabulous.
The princess' new dark hair is a hit with fans too. Though she was known for her blonde pixie crop for many years, Charlene went to the dark side in April this year and royal watchers love her style change.
"I'm loving her hair these days," one fan wrote, with another agreeing: "This hair colour is definitely much better for her." A third agreed: "I love the darker hair as well."
