What fashion brand was co-founded by artist Justin Timberlake?

William Rast is an American clothing line founded by Justin Timberlake and Trace Ayala. It is most known for their premium jeans. On October 17, 2006, Justin Timberlake and Trace Ayala put on their first fashion show to launch their new William Rast clothing line. The label also produces other clothing items such as jackets and tops. The company started first as a denim line, later evolving into a men’s and women’s clothing line. The name "William Rast" is a combination of Timberlake's grandfather's first name and Ayala's grandfather's last name.

The 2007 line contained cord jackets, cashmere sweaters, jeans, and polo shirts. The pair reports inspiration from fellow Memphis native Elvis Presley: "Elvis is the perfect mixture of Justin and I," Ayala says. "You can go back and see pictures of him in cowboy boots and a cowboy hat and a nice button-down shirt, but then again you can see him in a tux and a collared shirt with rhinestones on it and slacks. We like to think 'If he was alive today, what would he be wearing?'"

Target has announced that a William Rast collection, including denim, outerwear and sportswear for men and women, would launch in December and be available for a month. In 2015, the clothing line earned him a Lord & Taylor's Fashion Oracle Award at the Fashion Group International's Night of The Stars Gala.
