Is there some secret sisterhood of Royal dress sharing we mere mortals are kept in the dark about? Pippa Middleton wore a dress to the Wimbledon finals on Sunday previously spotted on Princess Mary of Denmark. The printed frock with elbow-length sleeve and ladylike knee-length skirt is from Project D, Australian popster Dannii Monogue's label.
