Celebrations continued overnight in London following the marriage of Prince William and Kate Middleton.
Newly-wed Kate, the Duchess of Cambridge, switched into a new Sarah Burton outfit for her wedding party at Buckingham Palace tonight.
The dress is a strapless white satin gazar evening dress with a circle skirt and diamante embroidered detail round the waist. She is also wearing a white angora bolero cardigan.
The Duchess of Cambridge said tonight: 'I am glad the weather held off. We had a great day.'
Some 300 of the couple's closest family and friends will celebrate with dancing and dinner at the black tie event, which will stretch into the early hours.
The State Rooms, including the Grand Ballroom, are being used for the reception.
Almost 2,000 guests attended their wedding ceremony at Westminster Abbey this morning.
There were still thousands of well-wishers on the streets of central London this evening.
This afternoon, the prince, at the wheel of an Aston Martin, drove his bride out of the gates of Buckingham Palace to roars of approval from the waiting crowds.
Earlier, after a ceremony at Westminster Abbey lasting about 75 minutes, the couple travelled back to the palace in an open horse-drawn carriage.
After time for some family photos, they emerged on the palace balcony for the kiss that has now become a tradition of modern British royal weddings.
Queen Elizabeth II and Prince Phillip have already taken their leave and left for a quiet weekend elsewhere in Britain.
Buckingham Palace has announced that the couple will receive the title of Duke and Duchess of Cambridge.
William also becomes Baron Carrickfergus and Earl of Strathearn.
Over 1,900 guests - including heads of state and celebrities - were invited to the ceremony.
It was the biggest royal wedding celebration in Britain since the marriage of Charles and Diana 30 years ago.
The streets around Westminster Abbey were packed with spectators from early this morning.
Kate Middleton, who spent the night with her family at a nearby hotel, was driven to the abbey in a Rolls Royce accompanied by her father Michael.
Police say more than 5,000 officers were on duty today as they carried out a massive security operation.
As he went into Westminster Abbey, Catholic Primate of Ireland Cardinal Sean Brady said his invitation to the wedding was a significant step in the normalisation process between the two countries.
Meanwhile, in Ireland the interest in the wedding was so great that the demand for electricity was altered.
The use of electricity fell as people gathered to watch the wedding and stopped using other electrical appliances.
Éirgrid said that is quite common during games involving Irish teams in events such as the football World Cup or rugby grand slam matches.
