What do you do if you can't find the perfect motorcycle jacket? Well, if you're Amanda Thomas of Luv Aj, you make it. The jewelry designer has been churning out covet-worthy baubles for the past 10 years—to great success, we might add, as Miley Cyrus even wore Luv Aj rings in the viewed-over-330-million-times We Can't Stop video—but she recently decided to venture into a whole new territory: leather. "I felt the urge to try something new and challenge myself this past year," Thomas said. The result? A 25-piece collection complete with bomber and moto jackets, iPad and computer cases, each as cool as the next. We recently chatted with the designer about launching the new leather collection, her hands-on approach to business (she still ships out orders herself) and jetting to Bali.
