Christian Siriano is on fire. Michelle Obama wore one of his dresses during her speech at the Democratic National Convention; the designer launched a bridal and plus-size collection earlier this year, and the 30- year-old just presented a spring show of chic cocktail dresses and stunning, colorful gowns to rave reviews.

But the big talker this season: his diverse model line-up. In a Fashion Week that kicked off with a scathing op-ed in the Washington Post by another “Project Runway” alum, Tim Gunn criticizing the industry on it’s lack of options for average size women, it was both refreshing and reassuring to see a designer step up. Not only did Siriano cast models of various sizes, but he featured an ethnically diverse lineup, as well. We caught up with Siriano right after his show.

Why did you decide to include plus-size models in this season?

It was all about diversity this year. We wanted different ethnicities and women of all shapes and sizes. I just think that’s what’s happening right now in the world. There’s a lot of hate going on. So it isn’t about having plus-size women, it’s about celebrating everyone. Fashion is fun and it should be that way.


We loved the glam gowns, tell us about them.

We looked at a lot of vintage photos from the ’60s and ’70s of Jackie O in Capri on holiday. I was trying to give my customer that perfect holiday — and pack her bags for her.

When did you find out Michelle Obama was going to wear your dress to the DNC?

I was on my sofa watching. At first I didn’t even know it was mine, because I was nervous. I was like ‘that’s probably not it, but it looks really similar.’
