Chelsy Davy plans to look twice as nice for Prince William
and Kate Middleton
's wedding and reception.
Italian fashion designer Alberta Ferretti has revealed that Davy, 25, the off-and-on girlfriend of Prince Harry
, will wear two tailor-made Ferretti dresses on Friday – one for the ceremony and one for the evening party.
"The colors I have chosen are all in the blue and green tones which match perfectly with her eyes, hair and skin tone," says Ferretti. For the ceremony, she will wear an aqua green bias reverse satin dress, along with an aqua green faille silk jacket with a deep boat neck and a knot detail.
For the evening party, she will switch to a one-shoulder midnight blue crepe satin gown with a cut-out detail on the back.
"Having the fitting in Chelsy's flat in Chelsea was real fun and exciting. She's such a modern girl, full of life and very charming," Ferretti tells PEOPLE. "I'm sure she will wear at her best the special outfits that I have created exclusively for her and this momentous occasion."
Having broken up in 2009 after five years together, Davy appears to be back with Prince Harry
. She's been spotted on several shopping excursions
this week as she prepares for the wedding.
