The prince and his wife, the Duchess of Cambridge, sporting a favourite LK Bennett suit and with several inches lopped off her famous locks leaving her with a glossy long bob, were at the 23rd ICAP annual Charity Day in the City of London.
The fundraising event sees the global brokerage firm donate a day's revenue and commissions to charity, with the staff dressing up to complete their trades.
Some of the organisations supported by the Duke and Duchess are set to benefit this year - SkillForce, of which William is patron, as well as SportsAid and Place2Be which Kate represents.
It was, he admitted, one of the 'more surreal' moments in his life.
Standing next to a line of men dressed in smart jackets, denim hot pants and heels, Prince William managed to gain his composure enough to secure a deal worth 500 million Czech Krona.
