Storm in a DD-cup: lingerie-clad Ashley Graham hits the runway

She's worked with the likes of Levi's and has appeared to great acclaim in the Sports Illustrated swimsuit edition. 

But when Ashley Graham sashaying down the Fashion Week runway in New York – a platform which ordinarily champions very slim women – she really caused a storm.

Walking for Canadian retailer Addition Elle, the size-16 beauty was not only the star of the catwalk – she also designed the lingerie being showcased. 

Entitled Black Orchid, her collection includes black, blue and purple bras, corsets, and underwear – all of which have been specifically designed to complement the curves of fuller-figured women. 

Ashley, 28, is also a body-positive activist and during yesterday's show, guests were encouraged to use the hashtag #IAmSizeSexy to promote body diversity.

Speaking to the Huffington Post in advance, Ms Graham described the #IAmSizeSexy drive as an "amazing, all-inclusive, high-end fashion campaign".

She also said: "Everyone deserves to see themselves being represented equally."

And taking to Instagram after the show, the US model stated: “What an amazing experience!! All the girls looked amazing," adding: "Thank you to everyone who was involved behind stage as well! We rocked it! #IAmSizeSexy."

In further Instagram (a platform on which she boosts 450,000 followers) snaps today, Ashley also said that her "curves and lingerie" had slayed the runway. "Still pinching myself!!" she went on to say.

Meanwhile, the Addition Elle label stated that "history was made!"

"Curves took over the runway at #NYFW. Thank you to everyone who made this possible!

"And thank you to all the delicious curves that strutted their stuff and who showed the world what #iamsizesexy means!"
