Project Runway winner Christian Siriano outfitted First Lady Michelle Obama in the elegant, cobalt blue dress she wore to the Democratic National Convention last night (July 25), where she publicly endorsed Hillary Clinton for the U.S. presidency. While her dress was understandably overshadowed by the speech Obama delivered -- which effectively eviscerated Republican nominee Donald Trump without ever mentioning his name -- make no mistake: her decision to wear a Christian Siriano design was likely a measured one.

Not only is Siriano an American designer, but he's never shied away from working with women of all ages and sizes -- something largely unheard of in the fashion world. As the New York Times points out, his message of inclusivity is one that was echoed time and again throughout Obama's speech.

Siriano -- who recently made headlines when he designed a gown for actress Leslie Jones after she put the fashion world on blast last month by revealing no designers were clamoring to work with her for the Ghostbusters premiere -- commented on Obama’s decision to contract him for several pieces, and he arrived at a similar conclusion.

“My mission was always, ‘Let’s support everybody. You never know who a great customer is going to be,’” Siriano told Vogue. “Growing up, my mom was a size 16 to 18, so it was just normal to dress women of all sizes.

"I can only hope that’s why [Michelle Obama] chose to wear something and why she likes my clothes,” he continued. “We feel the same way about people.”
