The obi belt, part of traditional Japanese dress and considered most elegant when it’s tied in proportion’s to the wearer’s dimensions (with a width about one tenth of your height). After centuries completing the look of a kimono, the obi belt is a must this season, whether you need one for a new fall dress or just want to update your faithful LBD.

Why has the obi withstood the test of time for hundreds of years? This customary belt happens to be the most flattering: it accentuates a small waist if you’re lucky enough to have one, or with the graduated large-to-small layers, it gives the illusion of a slimmer waist. Roland Mouret has a kimono-inspired textured silk gown dedicated to this look, but for real versatility, just get the belt and mix and match to your content! Dainty and precise or casual and loose, the obi is anything but restrictive.
