I'd certainly go longer and hem up the difference/wear taller sandals. 180 cm will be at least an inch or two too short. From what I recall of my hakama-wearing jiujitsu instructors, hakama sit around the tops of the feet or a little below the ankle bone. 180 on a 188 cm person will have them sitting closer to the tops of the ankles like too-short pants.
