Everyone makes effort when dressing for a wedding - whether as a guest or in the bridal party - but when it comes to celebrities some would say there's such a thing as too much effort. Last year, Kendall Jenner was a bridesmaid for her friend Lauren Perez, and did an evening outfit change that included a rather risqué dress with diamond-shaped cut-outs. After Instagram blew up with comments, Jenner actually addressed her critics. According to People, Perez waded into a conversation on social media to defend the dress, saying: 'Tell em! SHE LOOKED STUNNING AND I LOVED IT!' Jenner herself then replied with, 'Obvi asked for your approval in advance too. We love a beach wedding.'
That seemed to put an end to that particular conversation, but she's not the only one who has ventured into 'upstaging' territory when it comes to a friend's big day.
To attend the wedding of Britney Spears and long term Sam Asghari, Paris Hilton opted for a floor length shimmering black cut-out gown with thigh high split. What would you expect from Paris Hilton! With Donatella Versace in attendance and Versace also creating Britney's custom wedding gown, it seemed only fitting that Paris' look was, of course, Versace, too. What with Kravis' Dolce and Gabbana Italian nuptials and Britney's Versace-clad guests, it seems bringing on board a fashion house dress your ceremony is the A-Listers way to do weddings this year!
And the bridesmaid wore... Vera Wang! Paris Hilton isn't the only one opting for a more 'controversial' wedding outfit. Earlier on this year Ariana Grande attended the Star Wars-themed wedding of her equally-famous brother Frankie Grande wearing a crop top and skirt with thigh-high split. While some may argue it's a little show-stopping for family nuptials, it did feel rather perfect for a fun-filled celeb wedding. The singer paired her lamé sculpted top and skirt with her signature half-up style accessorised with a bow - somewhat reminiscent of her own wedding day look (which was also created by Wang).

Paris Hilton wears shimmering Versace gown to attend the wedding of Britney Spears and Sam Asghari in Los Angeles.
Sister-of-the-groom Ariana Grande turned heads in a lamé Vera Wang ensemble for her role as bridesmaid for brother Frankie Grande's _Star Wars-_themed wedding (that was on 4th May, natch).
How would you feel if someone arrived at your wedding wearing Schiaparelli Haute Couture? Probably thrilled if that person was Adele, sure, but perhaps slightly miffed that you weren't wearing earrings shaped like molars.
For Paris Hilton's wedding last year, her former assistant pulled out all the stops in a plunging gown from Rick Owens (and hip-high sock boots from Balenciaga).
Olivia Palermo turned a blind eye to the rule that almost everyone follows: never wear white to someone else's wedding. If we had the option to wear puff-skirted Giambattista Valli, perhaps we'd make the same call.
Marc Jacobs' wedding was pretty much a free pass to wear whatever you want - the more fabulous the better - but this might have been an eyebrow-raising look at less fashion-forward nuptials, no?
Kendall Jenner perhaps mistook her friend's wedding for the VMAs, arriving in what can only be described as a naked dress.
Sister Kylie Jenner looked spectacular for the wedding of 2018 - Hailey Baldwin and Justin Bieber's - but the thigh-high slit and cut-out, together, are perhaps more suited to the Golden Globes.
