It’s Hollywoods most glamorous night of the year, but despite months of rigorous planning, fashion at the Oscars can go very, very wrong.

Over the years the Academy Awards red carpet has seen many an A Lister fall victim to a whole number of sartorial disasters from nip slips to knicker flashes - proving they are only human after all.

As anticipation builds for the 2018 Awards on Sunday, we take a look back at some of the most scandalous fashion fails of all time.

Legendary actress Liza Minnelli turned heads when she bravely went bra-less on the red carpet, reports the Mirror.

Back in 2014, Liza suffered an unfortunate wardrobe malfunction when her nip-shields were exposed through her top.

The 71-year-old star was aiming to get noticed dressed head to toe in striking blue - and even sporting a matching streak in her hair - but her decision not to go sans underwear became the talking point instead.

Poor Mariah Carey became victim to a fashion fail when she headed to the Vanity Fair after party in 2017 - suffering the dreaded nip slip.

While the pop diva looked stunning in a jungle print gown, the plunging neckline could barely contain her ample bosom.

Mariah seemed totally unaware her nipple was on show as she happily posed up for photographers before heading into the star-studded bash.

The star also drew attention to her cleavage with a stunning diamond-encrusted gold necklace, and showed off some leg with a split in her dress.

In a sea of flowing ballgowns, actress Blanca Blanco opted to go underwear free at the 89th annual Academy Awards last year.

And the star suffered an almighty wardrobe malfunction in her extreme thigh split dress.

As she posed for pictures, the yellow and gold embellished frock fell open, revealing a lot more than she probably bargained for.

Fortunately, brunette Blanca didn’t seem fazed by the serious fashion faux pas and continued to smile for camera.

2015 was the year Oscar night gowns went rouge and raised a few eyebrows.

Emma Stone , 27, exposed her underwear in a dress slashed to the thigh.

Struggling to walk in her floor length gown the La La Land actress inadvertently flashed off her nude knickers as she held her gold Elie Saab sequinned gown off the ground.

At the 2012 Academy Awards Jennifer Lopez took to the stage with Cameron Diaz to present two awards.

Unfortunately, it wasn’t just the winners that got viewers talking.

Eagle-eyed fans noticed that JLo’s nipples appeared to be making a break for freedom under her plunging silver gown.

The singer’s stylist later spoke out to dismiss the reports about her custom-made dress and said it was merely a shadow viewers were noticing.
