Prince Harry's +1 to the Royal Wedding will be on-again-off-again girlfriend Chelsy Davy -- and we know what she'll be wearing to the big event.
While Kate Middleton's dress is shrouded in mystery, designer Alberta Ferretti revealed the 25-year-old will wear two of her original creations -- one for the ceremony and another for the reception.
Ferretti tells ABC News Chelsy will wear the satin, aqua green number below. The designer says it will be "teamed with an aqua green faille silk jacket with a deep boat neck and a knot detail."
As for the evening party, Davy will wear a one-shoulder midnight blue satin gown with cut-out details in the back.
Check out both designs below:
