Project Runway has crowned Erin Robertson its fifteenth-season champion.

Erin, a 29-year-old designer from Provo, UT, who currently resides in Cambridge, MA, was declared Project Runway's winner after she delivered a collection on the runway for New York Fashion Week that was viewed as innovative, unique and quirky by judges Heidi Klum, Nina Garcia, Zac Posen and guest judge Zendaya Coleman.

"OMG!!! I FREAKING WON PROJECT RUNWAY SEASON 15!!!! I'm so thankful to so many people who helped me through this experience. It's the hardest and most rewarding thing I've done and I couldn't have been this successful without the help of my community and family! S/O to all these models who look amazing and more importantly have beautiful souls. I'm so grateful!" Erin captioned an Instagram photo of herself standing in the middle of models who rocked her collection on the runway.

Erin's designs featured a playful use of colors and sequins that reflected her own signature style. She had a lot of wow pieces in her collection that Zac described as "pop-glam, art school, cut and paste."

Erin defeated finalists Laurence Basse and Rik Villa from Los Angeles, CA, and Roberi Parra from Miami, FL, in Thursday night's finale broadcast on Lifetime. Tim Gunn served as the contestants' mentor this season per usual.

For winning Project Runway, Erin receives $100,000 to launch her own business, a year's worth of Sally Beauty products along with an additional $25,000 cash prize, travel and hotel accommodations to inspiring destinations around the world from Best Western Hotels and Resorts, and an entire year's worth of Mary Kay beauty products for her fashion show and professional makeup-artist services for her debut show.

Erin also earned herself a brand new Lexus IS sedan, a complete sewing and crafting studio from Brother Sewing and Embroidery, and a fashion spread in Marie Claire magazine.
