ABC News' Bethany Owings reports:

She's known for duck calls and camouflage, but "Duck Dynasty" star Sadie Robertson has gone from the swamps of Louisiana to the glitz and glamour of New York's Fashion Week, all part of a trend to encourage teens to dress more modestly.

The 16-year-old daughter of Duck Commander CEO Willie Robertson took to the runway Sept. 9 to model her new fashion line, Sadie Robertson Live Original, a collaboration with top designer Sherri Hill.

"They're things that Sadie enjoys wearing," Hill told ABC News. "They're very feminine, very girly. Sadie's an athlete but she has a girlie side, too."

10 Things You Didn't Know About 'Duck Dynasty'

Fans of A&E's hit reality series might remember last season when Sadie was searching for a homecoming dress and earning dad's seal of approval wasn't exactly easy.

So the young "Duck Dynasty" star took to designing, factoring in her dad's opinion, telling Us Weekly she followed three simple rules when designing: "It's got to be long enough … The finger-tip rule … ," making sure her dresses are "daddy-approved" and, as for the neckline, she says, "Everything modest up here."

And that's something most parents can agree with.

"It is so important to get your parents involved in how you dress," Tammy Gold, a parenting expert for MommyCoach.com, said. "Studies show that girls that have a strong self have a nice and close relationship with their dad."
