Princess Beatrice exuded timeless elegance in an all-black monochrome outfit for Ralph Lauren's Holiday Celebration party, pairing a black velvet maxi dress with an oversized blazer for a contemporary and modern look.

Monochrome outfits are really having their moment this autumn/winter season, with a whole range of celebrities stepping out in striking one-toned looks - and Princess Beatrice just gave a masterclass in styling the one-colour trend for more formal occasions.

Stepping out in London for Ralph Lauren's Holiday Celebration in support of The Royal Marsden Cancer Charity, Beatrice stunned in a head-to-toe designer look that utilised a number of winter capsule wardrobe staples to create a timeless festive party outfit.

Shop Princess Beatrice's Look

For the base of her outfit, Beatrice wore the stunning new-season Velvet Scoopback Dress by Polo Ralph Lauren, with the simple and timeless crew neckline, practical long sleeves and fit-and-flare silhouette oozing sophistication. The versatile party staple is one that can be worn time and time again across seasons, with the simple all-black look being elevated by both the soft and luxe velvet fabric and the unique statement scoop back that shows off just enough skin to give a contemporary feel while still in keeping with a classic style.

Beatrice covered up this scoop back detail with the Polo Ralph Lauren Double-Breasted Silk-Lapel Wool Blazer. This style of tailored blazer is a staple in the cooler months, with the crisp and timeless double-breasted silhouette working to elevate numerous different outfits. It looks great thrown over a fitted and formal dress to add a touch of elegance to a party look like Beatrice's and you can experiment with doing up the buttons or leaving them open to create different silhouettes and we love the oversized fit Beatrice has played with that brings a youthful feel to the formal style.

Accessorising her monochrome outfit, Beatrice kept it simple and pared back for a sleek and sophisticated look. With just a simple pair of small gold hoops in her ears, a scattering of gold rings on her fingers and a pair of sleek, black pointed-toe heels on her feet, it was Beatrice's crossbody bag that was left to shine. The Ralph Lauren 888 Box Calfskin Crossbody from the Ralph Lauren Collection is a timeless designer style, and at £2,265 it's one of the more affordable designer handbags on the market right now.

We love the classic box style that works with Beatrice's minimal monochrome outfit perfectly, with the sleek black leather, signature RL monogram closure and shining silver hardware drawing the eye without overwhelming the look.

We're not the only ones who love the look, with fans of Beatrice taking to Instagram and X to praise the classic and timeless outfit, with one even saying that the outfit is 'one of her best looks' ever - and we might have to agree!
