Prince William and Kate arrive at their first official engagement as a couple.

The Duchess of Cambridge arrived at a posh London fundraiser Thursday night in style -- stepping out of a blue Jaguar. 

Sure, she had a sweet ride and a handsome husband on her arm, but all eyes were on her sparkling pink gown, a floor-length organza number by British designer Jenny Packham. The $6,000 gown was purchased off the rack, according to the palace. 

The party was the first official engagement for the couple, who were the guests of honor at the charity dinner to benefit the Absolute Return for Kids foundation. For more -- and for news on whether Harry's getting married anytime soon -- watch TODAY's report!
