Broadcaster Marian Finucane threw tradition to the wind when she wed her long term partner John Clarke in a slate grey and black frock coat. Here are some other leading ladies who went against the grain:
Screen legend Elizabeth Taylor was married an astonishing eight times, so it’s hardly surprising that wearing white became a bore. For her 1964 marriage to Richard Burton, she broke the mould in a canary yellow dress by Edith Head, accessorised with a fresh floral headpiece.
The innately elegant Audrey Hepburn also defied convention when it came to her second time saying ‘I Do’. The actress wore a simplistic mini dress and flat pumps to show off her waifish figure when she wed Andrea Dotti in 1969. She finished the look with a headscarf and bouquet of snowdrops.
One of the most iconic wedding looks of all time was the one worn by Bianca Jagger to her 1971 St Tropez nuptials to Rolling Stones frontman Mick. The bride opted for a sultry white skirt suit and wide-brimmed hat.
In typical rebellious fashion, No Doubt singer Gwen Stefani got hitched to Gavin Rossdale in a white gown with pink dip-dyed train by maverick designer John Galliano.
Like Marian, actress Sarah Jessica Parker turned her back on tradition and decided to wear black for her big day. The Sex and the City star has since said she deeply regrets her choice of outfit for her 1997 wedding to Matthew Broderick.
Similarly, 90210 actress Shenae Grimes said her vows to Josh Beech in a black chiffon dress by Vera Wang.
She might have millions in the bank, but when it comes to sustainable fashion - Keira Knightley is one resourceful woman. The actress wore a Rodarte mini dress for her 2013 wedding to James Righton. Impressively, it was a dress she had previously worn to premieres and parties and she has also been spotted in the blush pink number since.
Well when you have legs like those, it would be a shame to hide them. Amazonian supermodel Anja Rubik rocked a Pucci mini dress when she married her model fiancé Sasha Knezevic in a Spanish ceremony in 2011.
Burlesque pinup Dita Von Teese is known and applauded for her inimitable style. For her 2005 wedding to rocker Marilyn Manson (they wed in a gothic castle in Co Tipperary) she wore a rich violet satin dress by Vivienne Westwood.
Iconic supermodel Cindy Crawford tied the knot with Rande Gerber in 1998. For their lowkey, barefoot beach wedding she wore a delicate John Galliano slip dress.
Another couple who also wed on the beach were Pamela Anderson and Kid Rock. For her big day in 2006, the buxom blond threw the rule book out the window and wore just a white bikini and sailor hat.
For her 2014 wedding, the ever innovative Solange Knowles arrived on a bicycle and changed into a jaw dropping number by Kenzo. With her eye-catching afro, statement red lip and gold cuffs, this was one of the most memorable wedding looks of recent years.
Being the style maven that she is, Olivia Palermo was never going to go for the whole ‘white meringue’ look. The fashion designer and socialite donned a cashmere jumper, shorts and tulle skirt as she got hitched to German model Johannes Huebl.
When Brad and Angelina finally tied the knot in a surprise ceremony, the actress divided opinion with her choice of dress. While the silk satin gown by Donatella Versace and Luigi Massi was classic and feminine, it featured a surprising twist - the illustrations by her children embroidered into the fabric.
