Wedding of Princess Alexandra and Angus Ogilvy

Prior to the service, the organist of the Abbey played pieces by J.S. Bach, G.F. Handel, Herbert Howells, and William Henry Harris. Princess Alexandra walked down the aisle on the arm of her brother, The Duke of Kent, to the hymn Holy, Holy, Holy. Throughout the service, the hymns God be in my head, and in my understanding and Love Divine, All Loves Excelling were sung. The National Anthem was sung, and during the signing of the register, anthems by Christopher Tye, Thomas Weelkes, and G.F. Handel were sung. The newlywed couple recessed to Widor's "Toccata" from Symphony for Organ No. 5 and Walton's Crown Imperial.[5]

The bride wore a wedding dress of Valenciennes lace, with matching veil and train, designed by John Cavanagh. The lace had to be made in France, with special customs arrangements being made so that the press was not notified of its arrival in Britain.[4] The wedding dress included a piece of lace from the bride's late grandmother, Princess Nicholas of Greece and Denmark, and the veil worn by Lady Patricia Ramsey at her own wedding in 1919. She wore the diamond fringe tiara given to her mother by the City of London as a wedding gift in 1934.[4] The bridegroom wore morning dress.

The Queen wore a eau-de-nil dress with a matching three-quarter sleeves chiffon overcoat by Norman Hartnell and a hat by Simone Mirman. In 2016, The Queen's ensemble was on display during the exhibition "Fashioning a Reign" to celebrate her 90th birthday.[6]
