Like any bride, the Queen spent months planning her dream wedding to Prince Philip.
The Monarch, who was Princess Elizabeth at the time, spent the four months between her engagement and the day she walked down the aisle of Westminster Abbey organising every tiny detail – including the guestlist, the food and of course finding the perfect dress.
But however much planning goes into weddings, there are some things you simply can't control – and the bride found herself facing disaster just two hours before the celebrations were due to begin.
The Queen asked designer Norman Hartnell to make her dress, opting for a fit and flare ivory silk gown with a floral design, featuring 10,000 white seed pearls, silver thread, sparkling crystals and transparent appliqué tulle embroidery.

However the piece caused a lot of drama on the Queen's big day, when it snapped as she was getting her hair done.
She told the Duchess of Cambridge the story when the royal duo went to see an exhibition on Kate's wedding dress in 2011.
She said: "The catch, which I didn't know existed, it suddenly went.
"And I didn’t know it was a necklace, you see. I thought I'd broken it.

"We stuck it all together again, but I was rather alarmed."
Just two hours before the wedding was due to start, the tiara snapped in half as the hairdresser was fixing Elizabeth's veil.
The Queen Mother managed to remain calm and reportedly reminded her upset daughter "there are still two hours and there are other tiaras."
And luckily, this wasn't any ordinary wedding, and the royal family's jeweller was on standby just in case anything went wrong.

The team frantically welded the piece back together and got back to the bride just in time for her to have it placed on her head.
