The Royal Order of Sartorial Splendor has a fantastic post on the wedding.
Carolina’s stunning gown comes from Dutch designer Addy van den Krommenacker, who also dressed the bride’s mother and sister. The dress’ most notable feature is the heirloom Bruges lace, which was worn by Princess Irene at her wedding in 1964 and has now been adapted for use by her daughter (after an intense restoration effort by the designer). Accordingly, the design is named the “Irene”.
Thanks for the info. I love this picture of the wedding:
