Crown Princess Victoria attended her first official event after the announcement of her pregnancy with Prince Oscar. The event, The Sweden Dinner, was held at the Royal Palace of Stockholm on September 4, 2015. 

This is another find by Sarah. For this event, The Crown Princess wore an Adrianna Papell sequined gown, which retailed at the time for $358.

The Sweden Dinner was introduced in 2013 in celebration of King Carl XVI Gustaf's 40th anniversary as the King of Sweden. There were approximately 200 guests from all over the Kingdom of Sweden. It was held in the White Sea ballroom. 

Victoria's pregnancy announcement came on September 4, 2015. In the statement, the Royal Court said, "Their Royal Highnesses Crown Princess Victoria and Prince Daniel are happy to announce that The Crown Princess is expecting their second child. The birth is expected to take place in May 2016. No changes in The Crown Princess Couple's public engagements are planned during the fall of 2015."

Sarah also found that at this same event, Princess Sofia wore a red and nude colored lace dress by Dagmar.
