Prince Harry's longtime on/off girlfriend Chelsy Davy, 25, arrived to the Royal Wedding in style in London on Friday, April 29th. The blonde beauty wore a custom-made green Albertta Feretti dress. It's one of two dresses from the designer that Chelsy will be wearing today -- the other is a dramatic long navy grown for the reception.
