Kate Middleton in Elegant Green for St. Patrick's Day Celebration [PHOTOS]

Kate Middleton was probably the most elegant lady in the world to wear green on St. Patrick's Day.

On Saturday, Duchess of Cambridge attended a celebration and greeted Irish soldiers in Aldershot, England.

The 30-year-old fashion icon was radiant in her smile, pairing a green coat dress from Emilia Wickstead with a chocolate brown hat from Lock & Co. Her gold brooch was what the late Queen Mother wore in visiting the Irish Guards every St. Patrick's Day.

Kate presented 40 soldiers with a basket of shamrocks as a part of the tradition that dates back to 1901. Regimental mascot Conmeal, a six-year-old wolfhound, also received shamrock from the Duchess.
