Christina Aguilera's dress shows a lot of body — but not necessarily her own. While attending Vogue's Smart Tox event on 7 Sept. during New York Fashion Week, the singer stood out in a colourful naked illusion dress by the brand Feben. The design featured a green and yellow bodice à la the famous Venus de Milo, shaping Aguilera's own curves to look like the sculpture's. The original painting on the dress — created by artist Jaana-Kristiina Alakoski — included a vivid oil-slick of colours, dripping down from the top of Aguilera's neckline, all the way down to her long sleeves.

Styled by Chris Horan, Aguilera accessorised the bright bodycon ensemble with olive green sunglasses, a matching clutch, and metallic gold knee-high boots from Steve Madden. She left her long platinum-blonde hair down and completed the look with minimal gold jewellery to keep the attention on the art.

The naked dress trend originally meant showing skin through sheer fabrics, as seen with Florence Pugh's braless couture at the Valentino Couture show and Ciara's fishnet gown at the Oscars afterparty. But more recently, some celebrities have debuted much more literal interpretations, including Kourtney Kardashian, who in January wore a similar nude illusion dress with a Renaissance-era print. These nude optical illusions result in quite the sexy trend warranting a double take. Don't believe us? See Aguilera's colourful spin below.
