During her wedding to Lieutenant Phillip Mountbatten in 1947, then Princess Elizabeth suffered a wardrobe malfunction. However, thanks to her many attendees and her own ability to handle setbacks, she made it through the ceremony without ever hinting that she'd narrowly avoided disaster.

Elizabeth was using the Fringe Tiara, a special tiara borrowed from her mother which could also double as a necklace. Unfortunately, it malfunctioned while she was trying to put it on a few hours before the ceremony, and as a high-strung bride on a high-stakes wedding day, Elizabeth was understandably alarmed.

Fortunately, a jeweler had been placed on standby in case of a jewel-related emergency. The Fringe Tiara was taken across London with a police escort for repairs and was soon back on the Princess’ head; photographs taken from the day of the big event show her looking “calm and serene” as if nothing had happened.

The tiara's days of adorning the heads of women from the House of Windsor on their wedding day didn't end with Princess Elizabeth's marriage in 1947. In 1973, Elizabeth, now Queen, took a page out of her mother's book and loaned it to her own daughter, Princess Anne, when she wed Captain Mark Phillips; it’s unknown whether or not the accessory malfunctioned again.
