Excerpt taken from " The shy princess: The life of Her Royal Highness Princess Beatrice, the youngest daughter and constant companion of Queen Victoria" by David Duff describes the wedding dress in some detail.
"Princess Beatrice's wedding dress was of white satin, trimmed with orange blossom and lace, the lace overskirt held by bouquets of the blossom entwined with white heather. There was lace, too, on the pointed neck line, and on the sleeves, for the Princess was a lover of, and an expert on, lace. One of her most treasured possessions was a tunic of old point d'Alencon which had belonged to Catherine of Aragon. Knowing her daughter's love of lace, the Queen now bestowed a signal favour upon her. She allowed Princess Beatrice to wear the Honiton lace which she herself had worn on her wedding day...It was a very precious possession to the Queen, and Princess Beatrice was the only one of her daughters to be given the opportunity to wear it."
