--Previous Message-- : : Princess Margaret was wearing the Royal : Victorian Chain, which is unrelated to the : Royal Victorian Order. : : Since royal ladies don't generally observe : collar days (of which today, Easter Sunday, : is one) we probably won't see the Duchess of : Cornwall wearing the collar. However, HRH : will now have a sash to wear at gala events, : as seen below on the Countess of Wessex at : the Swedish Royal Wedding. : : :
