Margherita's family announced her engagement to Robert, Archduke of Austria-Este on 20 October 1953.[1] They married on 29 December 1953 in Bourg-en-Bresse, Ain, France (civilly) and 29 December 1953 (religious), in Brou, France.[2][3] He was the second son of former Emperor Charles I of Austria and Zita of Bourbon-Parma.

She wore an ivory gown made out of satin with a long train hung from a diamond tiara.[3]
