There’s a well-established belief that an engagement ring should cost three month’s rent. We’re not sure where it originated (or even why, as most people’s salaries vary so greatly to make it totally skewed) but luckily for anyone planning to propose this Christmas, the so-called ‘three-month rule’ has gone out the window for 2017.
According to US-based jeweller Anna Sheffield, the rules have ‘really shifted’ for millennials. She told the Metro: ‘The idea of any equation dictating what to spend on something this personal and special is kind of tied to that same status quo of a white diamond/white gold solitaire being the only ring to get. A solitaire is a classic, but it shouldn’t have to be a white diamond if you prefer black, or grey or champagne or even a moonstone for that matter. The idea of the engagement ring now, I feel, is more tied to values and integrity of the material and the maker, as well as the people who will ultimately own the rings. They are symbols of their love after all!’

While celebrities often cough up eye-watering amounts of money for their bling (Jay-Z reportedly spent $5 million on Beyoncé’s), the ‘average’ cost of a ring today doesn’t actually exist, as we are spending anything from £200 - £200,000, with the focus usually being on finding something uniquely tailored to the individual, rather than a big rock. Many couples even choose to design a ring together themselves, making the process less about showing off and more about symbolising the relationship.

Keira Knightley wore a knee-skimming tulle dress by Chanel couture for her low-key wedding to musician James Righton in 2013. Knightley chose to wear a dress she already owned (from the fashion house's S/S'06 collection) - and has since re-worn it for red carpet appearances. Well, if the dress fits...
Princess Margaret chose a silk organza gown by Norman Hartnell - the designer behind the wedding and coronation dresses of her sister, Queen Elizabeth - for her wedding in 1960. The tailored shape and lack of embellishment (a striking departure from previous royal wedding styles) lead Life magazine to crown it 'the simplest royal wedding gown in history.'
Queen Elizabeth II had to save up ration coupons to exchange for the duchesse satin used in her wedding dress, which was designed by Norman Hartnell and decorated in 10,000 imported pearls.
Jacky Kennedy's traditional wedding dress was designed by Ann Lowe, a designer favoured by American high society, and was made from nearly 50 ft of ivory silk taffeta.
Was there ever a more perfect wedding dress than Kate Moss's bias-cut, Thirties-inspired slip of a gown, custom made by her friend John Galliano? The designer later described the process of making Kate's dress as his 'creative rehab.'

It was the most talked about wedding dress of the century: Kate Middleton wore a long-sleeved Alexander McQueen gown, designed by creative director Sarah Burton, for her wedding to Prince William in 2011.
Designed by MGM costume designer Helen Rose, Grace Kelly's high-necked, long-sleeved gown was a clear inspiration for Kate Middleton's wedding dress. Worn for her 1956 wedding to Prince Rainer of Monaco, it was fashioned from 25 yards of silk taffeta, one hundred yards of silk net, and Brussels rose point lace.
Princess Diana's 1981 wedding dress is still one of the most famous bridal styles of all time. The fairytale gown, designed by David and Elizabeth Emanuel, was fashioned from ivory silk taffeta and antique lace, which had belonged to Queen Mary. The 25 foot train posed something of a problem, barely fitting into Diana's wedding carriage.
