17th century geishas were big fans of obi belts. Designed to define their waists while wearing a kimono, the Japanese-inspired accessory had figure-flattering appeal. A few hundred years later, they've become a key piece to complete all kinds of layered looks. Tying yours over a jumpsuit or cardigan is a modern way to wear the ancient eastern piece. Ada has a sleek and sophisticated line to stock up on, while the tassel detailing on B-Low The Belt's gives a playful edge.
