Matt McAllister holds the Guiness World Record for the number of shirts worn at one time. He managed to fit on a whopping 155 shirts, ranged from size small to 10XL. The entire process took 4 hours and added 100 pounds to his weight. I think that’s pretty damn impressive. You can watch the video below (don’t worry, it’s not 4 hours long, they condense the footage to just give a time lapse of each new shirt).
