Wacks 51 Cocobolo are the glasses worn by the one and only Jess. It was revealed on New Girls' official website.
"As seen on Zooey Deschanel’s character 'Jess' in FOX's hit comedy 'New Girl', this feminine design is inspired by the masculine styles worn by Buddy Holly and Roy Orbison. Handcrafted of polished beveled acetate, this retro optical frame features dual plaques on the frame front and substantial temples. Includes the Oliver Peoples logo plaque laminated at the temple end."
