Chelsy Davy, the 25-year-old girlfriend of Prince Harry, will wear two dresses to today's Royal Wedding of Kate Middleton and Prince William, reports CBS News. Chelsy Davy will be dressed in green, and then blue, when she attends the event that is set to be watched by 2 billion people worldwide.

Davy has enlisted the help of designer Alberta Ferretti to create two different gowns to wear to the ceremony and reception. For the wedding itself at Westminster Abbey, Davy will don an aqua green reverse satin dress, with an "aqua green faille silk jacket" and "a deep boat neck and knot detail". Once Kate and William are officially wed, Davy will change into a one-shoulder midnight blue crepe satin gown with cut-out detail on the back for the reception at Buckingham Palace. It has been reported that plans for the post-wedding party have raised eyebrows at the palace. Middleton's younger sister Pippa Middleton has been given the job of organising the event, allegedly opting for a disco balls in the 'Throne Room' and fast food vans serving "bacon butties" in the palace quadrangle.

Chelsy Davy and Prince Harry broke up back in 2009 after dating for five years, but their relationship appears to be back on. According to the UK's Daily Mail, she was spotted in London on Wednesday (27th April 2011) shopping for wedding accessories before "helping Harry with his best man speech".
