Blake Lively's Met Gala dress took an incredible amount of time to make

We're talking hundreds of hours here

Last night's Met Gala saw the A-listers of Hollywood flock to New York's Metropolitan Museum of Art for a sartorial celebration like no other.

The theme of the night was 'Heavenly Bodies: Fashion and the Catholic Imagingation' – cue all of the headwear – and saw the likes of Rihanna, Sarah Jessica Parker and Bella Hadid take to the red carpet in full costume.

Blake Lively's dress was no exception, an embroidered, bejewelled creation complete with an epic train, and was paired with a spiked headpiece that was very reminiscent of Narnia's White Witch.

The star, who recently caused a social media stir when she unfollowed husband Ryan Reynolds on Instagram, opted for Versace as her designer-of-choice for the night, and perfectly pulled off the red eyeshadow trend.

But can you guess how long her outfit took to produce, gemstone corset and all? Answer: an eye-watering amount of time.

In an interview back in March, Blake Lively revealed that her dress actually took more than 600 hours to make.

'This year's [gown] may be my favourite ever. They've already worked on it for 600 hours, and it's not done,' she told Vogue.

Lively also wore custom jewellery and shoes, designed by Lorraine Schwartz and Christian Louboutin respectively.

While we're not sure we'll ever own a gown that took several hundred hours to make, we can certainly dream.
