The dress was a white Francisco Costa for Calvin Klein gown decorated with 6,000 pearls. In fact Lupita doesn’t actually own the dress, since it was borrowed from Calvin Klein for the award show. The London West Hollywood hotel declined to comment. It’s supposed that the surveillance video cams will offer some valuable information to detectives.It’s not clear if the dress was insured and for which amount of money.
