Kate Middleton's Stunning Evening Gown

Only 650 people were invited to the Queen’s lunch reception, which was said to be a “very cozy” event, according to Alex van Straunbenzee, a friend of William’s.

“There was a wonderful relaxed atmosphere. I won’t say it was informal, but everyone was having a wonderful time.”

Another guest said that Charles gave a “lovely speech about his son” Prince William before cutting the cake.

After the event, Kate Middleton and her sister Pippa changed dresses to prepare for the dinner dance. Kate walked out in another stunning white Sarah Burton for Alexander McQueen dress while Pippa changed into a custom Alice Temperley emerald green gown .
