capes are usually much shorter then cloaks, real world capes are worn off the side, usually the shoulder, and rarely ever reach past the buttocks, cloaks are how us modern-day peeps see superhero capes, usually goes somewhere nearby the ankles. Fun fact about cloaks, if a swordsman didn't have a shield/buckler with him, he could use the cloak as a shield, it was surprisingly effective at blocking blows with a sword specifically.
