In 2005, Justin Timberlake co-founded the clothing line William Rast with his childhood friend Trace Ayala, per Oprah.com. As for that unique name, it's a tribute to two of the most influential men in their lives. "Trace and I are huge fans of our grandfathers," Timberlake explained. "William is my grandfather's first name, and Rast is his grandfather's last name. So we took the names, and put them together."

The brand, at its core, is all about denim. But for Timberlake and Ayala, the vibe of William Rast is inspired by their "favorite movie stars" while also "keeping true to the heritage of the south where we're from" — meaning Millington in Memphis, Tennessee (via The Hollywood Reporter). "So it has a lot of Americana, a lot of rock and roll, a little bit of biker culture mixed in with a little bit of the glamor of Hollywood."

Inspired by the likes of James Dean, Marlon Brando, and Memphis legend Elvis Presley (via Entrepreneur), William Rast teamed up with Target for a collection of premium jeans, clothing, footwear, eyewear, and jewelry (via The Independent), while their products were also available in Macy's, Nordstrom, Dillard's, Bloomingdales, and lots more (via People).
