The Duchess of Cambridge
returned to the designer of her iconic wedding dress for a pre-Christmas night out.
Kate, 29, wore a beautiful black Alexander McQueen gown as she and husband William
, also 29, attended "A Night of Heroes," an annual awards show to honor British servicemen and women, at London's Imperial War Museum on Monday.
She also wore jewelry she was given as wedding presents, according to an insider, at the event where 11 awards are presented to groups, individuals and units from the Royal Navy, Army and Royal Air Force.
Earlier in the day, Kate joined William and Prince Harry
at Buckingham Palace for their grandmother Queen Elizabeth's pre-Christmas lunch.
Later this week, the couple will visit to Centrepoint, a charity for the homeless, before heading to the Queen's country home at Sandringham, Norfolk, for the royal family's traditional Christmas gathering
