Lady Amelia Windsor was effortlessly chic as she sported a camisole and miniskirt for the Barbie: The Exhibition opening at the Design Museum in London tonight.
The royal, 28, donned a flowy pastel top, adorned with floral prints, for the event on Wednesday.
Sticking to the pink theme, she teamed it with a dusky pastel skirt, accessorising with beachy beaded necklaces.
The model wore her newly chopped blonde tresses down in a relaxed style and opted for dewy, natural make-up.
Adding a grungy element, Amelia - who is the granddaughter of Prince Edward, Duke of Kent - donned chunky black shoes to finish her ensemble off.
She also carried a fun, square-shaped clutch which appeared to resemble a dollhouse.
The exhibition will run from July 5 to February 23, and promises to delve into the 'design evolution of one of the world’s most famous dolls'.
The website reads: 'Journey into the Barbie universe and discover over 250 remarkable objects, with rare, unique and innovative dolls dating from 1959 to the present day.'
Getting into the playful spirit, Amelia posed inside a Barbie box shaped display at the event.
Also present at the event were a host of VIPs, including Lady Mary Charteris, who donned a hot pink gown.
Last month, the royal was spotted at a star-studded Vivienne Westwood event at Christie's London.
It saw the fashion elite gather at the auction house in London's St James for a private viewing of the archive collection.
Amelia, who is 43rd in line to the throne, looked relaxed in a stylish cropped jacket with a patent finish, black high-waisted trousers and a midriff-baring black crop top.
It's been a busy summer for socialites Amelia and Emma Weymouth who had also the Royal Academy of Arts Summer Exhibition party together recently.
Lady Amelia commanded attention in a vibrant purple gown as she stepped out at the lavish event in London.
The Dolce & Gabbana model, who is no stranger to premieres and launch parties, added an edgy feel to her outfit with a black handbag, designed like a cottage, and a pair of chunky flat shoes.
Adding a touch of glitz to her off-the-shoulder ensemble, Lady Amelia, who is cousins with Princes William and Harry, donned an array of glittering jewellery, from dazzling bracelets to colourful gem-filled rings.
Elsewhere, Emma, 38, looked equally stylish in an eye-catching scarlet maxi dress, featuring daring cut-out embellishments, a plunging V-neck and dainty straps.
The Marchioness of Bath teamed her daring ensemble with a matching red handbag and heels, whilst opting for a bright ruby lipstick to finish off her fiery look.
Emma no doubt turned heads in her dress, which featured a billowing skirt and cinched waist detailing.
She finished off her outfit with a shimmering pair of diamond earrings and an immaculate pink manicure.
Held every year since 1769, the RA's Summer Exhibition celebrates contemporary art spanning mediums including painting, printmaking, film and photography.
It is the world's oldest open submission exhibition, meaning anyone can submit their work to be considered for inclusion.
