Ancient Chinese knot-tying techniques and the It bag of the season may seem like an unlikely combination, but Katherine Kwei pulls it off. Drawing inspiration from her own Chinese heritage, she gives her line of hip handbags a personal twist with gorgeously crafted details like fringing and knotting. And with a background at Louis Vuitton, she’s well schooled in luxury. Some of Hollywood's most fashionable celebrities have already caught on: Sienna Miller, Taylor Momsen, and Blake Lively have been spotted out and about with these must-have hobos and satchels hanging off their arms.
