Lady Eliza Spencer is incredibly well-versed in the fashion department. If the aristocrat isn't frolicking at fashionable events with her stylish twin sister Amelia , she's often snapped on lavish romantic adventures with Greg Mallett, whom she married at Quoin Rock Manor House in South Africa back in 2023. On her latest luxe getaway, the 32-year-old, who is the niece of the late Princess Diana, shared snaps on Instagram from an ultra-chic staycation in London at the Savoy Hotel, wearing a dreamy two-piece lingerie set and putting a socialite seal of approval on the fashion set's favourite underwear trend of this season.

Eliza posed for the camera in an ethereal white slip mini dress with a delicate lace trim across the neckline and the hem, designed by luxury sleepwear label Bocan Couture. She paired her silky nightie with the matching short robe, featuring vintage-inspired lace panelling vertically adorning the opening of the garment. While Eliza's sophisticated white set is perfect for any bride-to-be, from the hen-do to the morning of the big day, it's also bang on trend for cool-girls who want to follow in the sartorial footsteps of Sabrina Carpenter and incorporate négligées into everyday outfits.
