Is Chelsy Davy Working a More "Royal" Look?

Is it possible that sexy Royal sweetie Chelsy Davy is trying to work a more high-end look? The English press seems to think so. Chelsy made her most high-profile appearance to date recently when her boyfriend Prince Harry was awarded a medal for bravery for his time in Afghanistan (presented by Harry's aunt Princess Anne). See the photo of Chelsy with Prince William and her demure look with brown boots. At a Polo match she chose a jacket with cinched waist the seemed very influenced by William's stylish girlfriend Kate Middleton. Could this all be rehearsal for tomorrow when Chelsy will allegedly be meeting the Queen at the wedding of Harry's cousin Peter Phillips (son of Princess Anne). William will be in Kenya on a previous engagement but Kate is expected to attend alone.
