Ashley Graham was a vision on the red carpet Friday night at the Harpers Bazaar annual Icons party , where she stepped out in a black feathered sleeveless dress.

The supermodel, who announced that shes pregnant with her first child last month, posed for cameras in a custom ensemble by 16Arlington. Her dress, with sheer material, featured a slit and a black feathery trim. Graham also opted for a black jeweled headband.

Graham posted photos on Instagram of her preparing for the event, dishing on details about her accessories.

I now understand the headband trend, she wrote.
