Christina Aguilera exploded on to the music scene in the late 1990s.
With her brand of catchy pop came a definitive sense of style, think crop tops, low-hung trousers, pleather and bright colours. It was a masterclass in late 1990s to early 2000s fashion.
The singer, 41, who first found fame as a child star in The Mickey Mouse Club, alongside Britney Spears, Ryan Gosling and Justin Timberlake, made a concerted effort to play with fashion early in her career.
"I'm a risk-taker and I've always been like that, especially when it comes to fashion," she said in an early interview.
After she left behind her casual two-pieces and chaps, Aguilera turned to labels such as Roberto Cavalli, Monique Lhuillier and Atelier Versace for colourful looks in her early red carpet appearances, when she dabbled in golden-era Hollywood stylings around 2004.
Far from loyal to one atelier, she has also sported designs by Elie Saab, Versace, Vanitas and Valentino for her more glamorous events.
As her career progressed, so did her style. Moving from her Genie in a Bottle era to Lady Marmalade, Dirrty and Beautiful, her music became grittier and so did her fashion. She moved away from prom dresses and gowns to more structured and bodycon looks, with lashings of pleather, leather and latex.
Pamella Roland, Marc Bouwer, Alexander Wang and Emanuel Ungaro were behind some of her most identifiable looks of the mid-2000s.
Later in her career, deep shades of black, red and purple made up the bulk of her sartorial colour palette for red carpet appearances, with the odd pure-white look thrown in for contrast.
Most recently, she has opted for directional pieces from Lebanese designer Nicolas Jebran, along with Helmut Lang, Balmain and Jean Paul Gaultier. The pink and red gown by Israeli designer Galia Lahav, which she wore to the 2020 Mulan premiere, stood out as a flash of vibrant colour.
As is the cyclical nature of fashion, Aguilera's early 2000s looks are very much on-trend once again, with low-hung waistlines, thin belts, crop tops, cargo trousers and exposed underwear making regular catwalk and red carpet reappearances on celebrities including Bella Hadid, Dua Lipa and Hailey Bieber.
