The Queen's sister even shunned tradition on her wedding day in 1960, when she said 'I do' to Anthony Armstrong-Jones. You see it's traditional for female members of the royal family to borrow tiaras from the royal vault for their wedding day. In fact, Princess Diana broke that tradition by wearing the Spencer tiara when she wed Prince Charles.
It seems like the took a leaf out of Princess Margaret's book, as she too did things her own way. She decided to buy her own jewels at auction, bidding £5,500 on a diamond tiara in 1959.
It originally belonged to the wife of the 3rd Baron Poltimore (also Margaret), and she actually bought the tiara before she became engaged, and wore it out and about several times before her wedding.
The tiara is also comparatively cheap compared to other wedding tiaras. It's said to now be worth around £40k, whereas Meghan Markle's wedding tiara was estimated at over a million pounds.
