MOST UNDERWEAR WEARED MAN ♂️👞
The official Guinness World Record for the most pairs of underpants worn at once is 266 pairs.
This record was achieved by Steve Jacobs in Sydney, New South Wales, Australia, on November 15, 2012.
To pull off a record like this, participants typically have to layer increasingly larger sizes of underwear—often ending with sizes up to 4XL or larger—to accommodate the massive bulk of wearing hundreds of layers at the same time.
