Apparently employees in Goldman Sachs' securities division are allowed to wear jeans in the office on August Fridays if they donated $25 to one of four charities.

'It’s been getting ridiculous,' said one female analyst, who asked not to be identified. 'Last Friday, there were traders walking around the floor with three buttons of their shirts undone, showing off their pecs and hairless chests.'" [Via Daily Intel]
