Ditto, singer of The Gossip and plus-size clothing designer in her own right, walked the catwalk in a white gown befitting a 1940s Hollywood movie star, alongside models of the moments, Bella Hadid, Kendall Jenner, and Lineisy Montero, as well as Emily Ratajkowski - who made her catwalk debut.
This isn't the first time Ditto has walked the red carpet, she previously made an appearance for Jean-Paul Gaultier at Paris Fashion Week in 2010.
Three years later she launched her own collection in Evans and she has voiced her support for the continuing conversation around plus-size models.
"I think it’s really important that people are talking about your body, because if they don't, then you’ll never be able to break that barrier," she told The Advocate.
Jacobs Spring/Summer 16 show was a theatrical display worthy of it's Zigfield Theatre setting, with a collection inspired by classic Hollywood glamour.
A star-studded audience was in attendance - with Winoa Ryder, Sofia Coppola, Kate Mara, Jamie Bell and Debbie Harry, watching Ditto take her turn.
So we're happy to see Ditto take her place among thinner models, however her appearance still felt tokenistic.
In 2013 Marc Jacobs was among the designers who were called out by the Diversity Coalition, an organisation that presses for more diverse representation on the runway, for not having enough models of color on the runway.
His Spring/Summer 2016 show may have been a step in the right direction, but the models of differing sizes and skin tones still seemed a little lost amid a sea of thin white models.
So while we were over-the-moon to see Ditto on the catwalk, all we can say is more Marc, more.
