Princess Beatrice was at the Mazi summer party with guest of honour Greek heiress Eugenie Niarchos, of jewellery brand Venyx World, in London on Tuesday.
The 25-year-old royal looked pretty incredible in a classic, satin LBD complete with crochet, fringed jacket, black stilettos and a matching black clutch.
Princess B played it effortlessly stylish in this all black ensemble but mixed up the texture to add a trendy edge. The kimono-style jacket? This look totally suits and makes a nice change from her regular throw-on cardi or blazer.
Eugenie Niarchos was everything you'd expect from a gorgeous Grecian. She did white on white in a three-quarter-length sleeve top and high waisted trousers with a metallic waist-belt. The laurel wreath headpiece made sure all eyes were on her, as did the killer red lipstick and edgy ear-cuffs.
That said, we're still wowing over Beatrice's look - she's even doing that fresh from the Spring/Summer 2014 catwalk hands in pockets pose.
It's official, this royal is all about moving in fashionable circles when she's not on royal duty (though her Royal Ascot style was immaculate) and last night's jewellery presentation was more proof of this.
