Alessandra Ambrosio ensured all eyes were on her when she made a surprise appearance on the runway at Julien Macdonalds Spring / Summer 18 show last night in a stunning creation inspired by luxury vodka brand CÎROC. Tipped as one of the most exciting and anticipated shows of the week, Julien Macdonald did not leave the front row disappointed...

Alessandra was a glamourous surprise addition to last nights star-studded fashion show, taking to the catwalk and dazzling in a beautiful CÎROC luxury vodka inspired dress. The CÎROC Utopia dress was designed exclusively for Alessandra by the legendary designer, tipping it as one of the hottest party looks to be seen in this year.

Julien Macdonalds cutting-edge designs for SS18 thrilled onlookers with a parallel universe concept. The new collection juxtaposes Juliens iconic, signature silhouettes with a futuristic, streamlined glamour. High-voltage, form-fitting pieces in molten shades of gold, silver, black and pewter interspersed with flashes of scarlet, ombre sapphire blue and yellow, transport guests to a modern Utopia.  An array of intricate beadwork, crystal mesh and lace appear on liquid sheath dresses, knitted catsuits and sports enhanced separates like an other worldly, embellished second skin. Nocturnal foliage motifs appear on flowing silk chiffon recalling the designers trip to the Amazonian rainforest and resulting in a captivating fashion experience in the heart of London.  

Earlier in the evening Alessandra joined guests of CÎROC vodka for an exclusive pre-show reception. Following the stellar display of models and show stopping looks, Alessandra took to the catwalk in the ultimate party dress to surprise the packed crowd of key media, celebrities and industry figures and reminded them why she is one of the worlds most in demand supermodels. Julien joined her on the catwalk and the pair celebrated one of the most vibrant moments of the London fashion season so far in a spectacular mist of metallic confetti as they closed the electric show.

Speaking afterwards Alessandra Ambrosio said, "What an incredible way to finale the wonderful week of celebrations in London! I was happy when Julien MacDonald designed this dress for me - especially one that is perfect for celebratory occasions! Wearing the CÎROC Utopia dress on tonights catwalk was an amazing occasion and definitely one of great on arrival moments to date!"

Julien Macdonald said: "My SS18 collection has been designed with elegant, strong and body confident women and men in mind and showcases looks that are inspired by a modern Utopia and my recent trips to the Amazonian rainforest. This season, I wanted to provide the ultimate balance between my signature high-octane red carpet wear and the sense of entering a new world.  I have given my second-skin, highly embellished pieces a stronger, sportier edge. Alessandra Ambrosio and CÎROC are the perfect partners to collaborate with for London Fashion Week as she embodies the powerful, independent women I dress and CÎROC represents the luxury lifestyle we all aspire to. I designed the CÎROC Utopia dress, featuring the brands signature ombré sapphire blue, to capture CÎROCs energy and On Arrival campaign."  

Alessandra was attending the fashion celebrations in London on behalf of CÎROC luxury vodka as part of the brands On Arrival campaign - an exciting partnership which follows her year of exciting arrival moments at the biggest fashion events in the hottest destinations around the globe. The collaboration spread its stylish wings last week releasing Alessandras beautiful Front Row look captured by the iconic fashion photographer Mario Testino. This follows the launch of the first look in the collection, Hair & Makeup, earlier this year, with one final killer visual to follow for the New Year celebrations later in 2017.
