Stepping into the Empire Hall of l'Hôtel de Paris, the South African-born royal exuded timeless elegance in a simple, yet sophisticated all-black dress adorned with gold details.
The former Olympic swimmer's eveningwear consisted of a boater neckline, billowing batwing sleeves and a sublime, full-length skirt that highlighted her statuesque frame.
The back boasted a vampy backless design, accentuating her feminine silhouette. Princess Charlene was wearing the 'Elmo' dress by royally-loved brand, MaxMara. She teamed it with a 'Diamond Cocktail Leather Clutch Bag' from Jimmy Choo and a logo-engraved leather belt from the same label.
Adding to her natural beauty glow, the mother-of-two styled her creamy blonde pixie cut into a sweeping side part, revealing a dewy makeup combination of golden bronzer, rich blush and pink lipstick.
Prince Albert looked equally dapper in photographs, wearing a black tuxedo as he graced the red carpet arm-in-arm with his wife.
Taking to Instagram following the glitzy event, the Monegasque royals penned on their official @palaisprincierdemonaco account: "This exceptional dinner was orchestrated by four star chefs Alain Ducasse, Yannick Alleno, Marcel Ravin, Dominique Lory and their teams.
Royal watchers were encapsulated by Princess Charlene's effortless style, flooding the comments with words about her sartorial prowess.
"Princess Charlene is a breathtaking beauty," wrote one fan, as another agreed: "Princess Charlene is magnificent."
A third wrote: "The dress is so chic, understated elegance is always a win, and the belt adds the perfect touch of simple styling that this look needs. Impeccable."
The Princess' glamorous appearance comes just weeks after she made a low-key appearance in skinny jeans at the Rugby World Cup in October. The proud athlete cheered South Africa as they clinched victory against New Zealand at the Rugby World Cup Final in Paris.
In photographs captured from inside the Stade de France, Princess Charlene and her husband Prince Albert of Monaco engaged in a rare public display of affection as they celebrated the Springboks' triumphant win.
