Sadie Robertson, the 18-year-old star of the popular reality TV show Duck Dynasty returned to the runway at the Sherri Hill show at New York Fashion Week on Sunday, Sept. 13, to strut the designer's new collection, reported Us Magazine.

Robertson proudly walked the runway with her famous smile as the conservative teenager showed the world she could be sexy too, but still remain classy. The author of Live Original wore three sets of Sherri Hill collections, including a crop top.

Robertson wore a white lace top matched with a pleated mini skirt in a sky blue hue and an embroidered halter top, and a ruby spaghetti-strap crop top. The dress was highlighted with a ball skirt (with pockets) in a sky blue shade.

Before the event, Robertson was seen on backstage wearing a red crop top, "a cherry-printed A-line skirt, and peep-toe heels while getting glammed up," the magazine reported. True to her sweet personality, Robertson gamely posed for pictures with other celebrities who participated in the event.

Robertson shares her experience at the New York Fashion Week on her Instagram by posting a picture of her with Miss USA Olivia Jordan and Miss Teen USA Katherine Haik. She captioned the post, "SO MUCH FUN and I didn't even trip until I got back stage and only Katherine saw it so we cool."

This was the second time that Robertson has graced the Sherri Hill runway. Sadie previously modeled Sherri Hill's cerulean gowns at the Fall 2015 show last February.

Sherri Hill's exclusive collections epitomize the fashionable lifestyle of today's contemporary women. Each look is designed to enhance and fit the female form with fashion-forward styling and wearability. Sherri Hill was recognized as one of the Top Ten Trending Fashion Designers, solidifying her place among fashion greats.

Sadie Robertson Launches Wild Blue Denim

Meanwhile, Robertson has announced a photo shoot with Wild Blue Denim. Teenage blogger Justina from A Bent Piece of Wire recently sat with Sadie for a one-on-one interview with the reality TV star and Dancing With The Stars alumni and discussed everything from her go-to outfit to her major love of all things denim.

The jean, tops, and jackets brand officially launches in Rue21 stores and will be available online November 13th. Sadie has her own fashion collections and the Wild Blue Denim is her way of branching out.

"Wild Blue Denim, the geniuses behind both this shoot and the only pair of ripped jeans I haven't promptly wanted to rip off my body, are just getting started. I got a chance to peek through their debut collection (aka when everyone was paying attention to Sadie I ran through it) and was impressed. These are jeans for the people to live in. This was immediately put to the test when I managed to snag them on the stool I was sitting on, not once, but twice. There is none of the cheapness usually found in ~juniors~ brands. You know what I'm talking about. The 'jeans' that are actually just scratchy plastic POSERS that you can see your knees through. Or, my personal favorite, the 'high waist' that ends halfway between your waist and your high-waisted happiness. That game is done, I am calling a winner, and it's Wild Blue," Justina writes in her blog.
