Kate Middleton and her sister Pippa Middleton took in the action last night at the 80s inspired Day-Glo Midnight Roller Disco charity event in London.  Kate, one of the organizers of the fund raiser to benefit the Children’s Hospital in Oxford, wore vintage yellow hot pants and bright pink leg warmers.

Middleton did take a tumble during the evening and ended up sprawled on the floor.  The event drew hundreds, including Holly Branson, daughter of English business magnate Richard Branson.  Princess Beatrice and her boyfriend Dave Clark were also on hand.

One photo shows Middleton being helped by several individuals.  Too much partying perhaps?
