In an age when curvaceous models like Kate Upton and "too curvy" Robyn Lawley grace the coveted covers of Sports Illustrated and Vogue, model Jourdan Dunn says her curves lost her a recent modeling job with Dior.

According to Dunn, her planned appearance in a recent Dior fashion show was cancelled because of her breast size, reported ABC News. “Ahahahahahaha I just for [sic] cancelled from Dior because of my boobs! I ❤ fashion #Couture” Dunn wrote on Twitter Sunday. Despite losing a position with the high-powered French fashion house, the 22-year-old England native said she is used to losing jobs, but it's usually because of her skin color.

The Dior haute couture event in Paris showcased the Fall/Winter 2013-2014 line, featuring bare- and small-chested models wearing sheer items, reported Star magazine.

According to the Sun, Dunn started her career 10 years ago at the age of 16 after being discovered while she was shopping for sunglasses in west London. While Dior allegedly passed on the British beauty, she has a history with other big fashion names, including Prada, Burberry, Gucci, Yves Saint Laurent and Victoria’s Secret.

Dunn isn’t the first model who has lost opportunities because of her bust size. 21-year-old model Kate Upton, labeled the “sexiest supermodel on Earth” by Vogue, confirmed to the mag in May that she'd been flamed for her natural curves. “The things that they’re rejecting are things that I can’t change,” said Upton. “I can’t change my bra size. They’re natural! I can work out and I can stay healthy and motivated, but I can’t change some things,” she said.

Dior has yet to respond to Dunn’s claims.
