Timberlake is teaming up for the William Rast collection with his best friend, Trace Ayala, and Danny Guez, who worked on Eve's Fetish and Bow Wow's Shago clothing lines, MTV.com reported.
William Rast is made up of the first names of Timberlake's and Ayala's grandfathers, MTV said.
While the clothes were actually designed by Juan Cervantes, Timberlake offered input for the upscale line described as down-home Tennessee meets Hollywood style.
The lines for both sexes includes jeans, T-shirts, polo shirts, sweaters, blazers and outerwear.
Bloomingdale's and high-end boutiques are expected to launch the line Nov. 3.
