However, a handful of A-listers have been known to ditch their day jobs for a spot of sartorial side hustling.
In previous years, celebrities such as Lady Gaga, Miley Cyrus, Elle Fanning and Kylie Jenner have graced the catwalks of some of the industry’s biggest designers, and for autumn/winter 2019, even more stars were subbed in for models.
At New York Fashion Week, we saw actors including Gwendoline Christie from Game of Thrones, Laverne Cox from Orange is the New Black, and Greta Lee from Netflix’s Russian Doll make an appearance on the runway.
Meanwhile, Philipp Plein’s show was taken over by an influx of musicians from Columbian singer Maluma to rapper Lil Pump and guitarist Luke Hemmings.
Elsewhere, supermodel Christy Turlington made a surprise appearance at Marc Jacobs, closing the show in a voluminous black taffeta gown.
Across the pond at London Fashion Week, A-listers-turned-models included actor Chloë Sevigny, who walked the runway at Simone Rocha and Gigi Hadid, who made an appearance on the catwalk at Burberry to present Riccardo Tisci's second collection for the brand.
