'Duck Dynasty' Star Sadie Robertson Walks Runway for New York Fashion Week / Partnered with Sherri Hill for Line of Prom Dresses [PHOTOS]

Duck Dynasty star Sadie Robertson is heating up the runway for her first modeling gig Monday during the Evening By Sherri Hill Spring 2014 show at the Trump Tower.

Instead of the family's normal camouflage attire, Sadie was wearing a black and white, floor-length polka-dot dress she helped design.

The young Robertson daughter looked as happy as could be strutting down the runway with her "daddy-approved" dress. The family recently partnered with Sherri Hill to design a prom dress collection that Sadie will spearhead. The line is called Sadie Robertson Live Original.

Sadie's mom, Kori couldn't be happier with the union.

"We're so proud and so happy about the partnership with Sherri Hill," the Duck Dynasty matriarch told Us Weekly. "She's been awesome. And they're a family business like we are, so we feel really great."

At the show, Sadie told Us Weekly that the main goal of her prom dress line was to make them one of a kind.

We're living original, that's our motto," the wholesome fashionista told the entertainment magazine.  "All our dresses are unique and represent who we are."

Ironically the young high-schooler is designing prom dresses, but has yet to actually attend one. After being asked by an upperclassmen at her school [watch out Willie!] Sadie will finally make her prom debut.

Now Sadie just needs to pick out her dress!

"[I'll pick] one of the dresses in the line. I don't know which one. It's so hard to choose."
