 Victoria settled an annuity on Louise shortly before her marriage . The ceremony was conducted at St George 's Chapel at Windsor Castle on 21 March 1871 , and the crowd outside was so large that , for the first time , policemen had to form chain barriers to keep control . Louise wore a wedding veil of Honiton lace that she designed herself , and was escorted into the Chapel by her mother , and her two eldest brothers , the Prince of Wales and the Duke of Edinburgh . On this occasion , the usually severe black of the Queen 's mourning dress was relieved by the crimson rubies and blues of the Garter star . Following the ceremony , the Queen kissed Louise , and Lorne – now a member of the royal family , but still a subject – kissed the Queen 's hand .
