To reverse simply pull up on the matte black buckle and twist. The first side is black with perforations and the other side is solid brown. Great for going from casual to dress in a snap. For the best fit please take your pant size and go up one (if you wear a size 34 or 35 order a 36 belt). Measures 1 1/8 inches or 28mm in width. Matte black twist to reverse buckle. Black side has fashionable perforations. Brown side is classically solid. Two belts in one for versatility.
