An article in Vanity Fair from 2018 quotes biographer Julie Baird on the lore of Queen Victoria making the white wedding dress popular. White had nothing to do with virginity or purity (at the time), but was a status symbol that the wealthy family could afford to have the dress cleaned regularly.
In Queen Victoria's pragmatic mind, white was simply the best option for her dress to show off the intricate lacework on the dress sleeves and bodice.

Queen Victoria wore an orange blossom and myrtle headpiece with an intricate lace veil. This deviated from the royal tradition of wearing a jeweled tiara.
Myrtle has been used in every royal wedding bouquet since Queen Victoria's wedding.
The garden where the myrtle has been harvested has recently been opened to the public.
