The dress code was super casual in Times Square yesterday as hundreds of people dropped their trousers and partied to celebrate National Underwear Day.

Frolicking in panties and boxer briefs, the flash mob attempted to best a Guinness World Record for the most scantily-clad partygoers in one place.

The Midtown crowd, sadly, could not beat Salt Lake City’s Utah Undie Run of 2011, which holds the current record of 2,700 people.
