Kendall Jenner showed she truly suffers for fashion after revealing that her skin-tight designer dress prevented her from walking up steps at sister Kourtney Kardashian's wedding to Travis Barker.

The 26-year-old model looked stunning in the fitted floral frock on Sunday, but showed the flawless look came at a cost – and not just the six-figure price tag.

On Sunday, Kendall's make-up mogul sister Kylie, 24, shared a video on her Instagram story of the catwalk star struggling to get up a steep staircase in the dress.

Mother-of-two Kylie, who gave fans a glimpse into the evening celebrations, could be heard laughing at her sibling's failing efforts to navigate the steps, which at one point included her legs wobbling awkwardly, before saying: 'S**t these stairs are crazy!'

It's not known if Kendall eventually got help up the stairs into the wedding reception, but Kylie later shared a clip of the pair dancing together and downing a shot in the venue to her TikTok account.

In the post's caption, Kylie wrote that Kendall was her 'cucumber girl' in a cheeky reference to a recent viral scene of The Kardashians, which showed the model's recent struggle to cut the vegetable.

The fun and frolics all went down at the reception in Portofino, Italy on Sunday afterKourtney and Blink-182 drummer Travis's lavish nuptials.

Kourtney, who wore a white minidress and elaborate veil at the wedding ceremony earlier, swapped it for a black version at the reception.

Sunday's ceremony, which took place next to the historic and stunning Castello Brown house museum that sits high above the harbour of Portofino, was the third time that the 43-year-old and the rocker, 46, have been 'married'.

They had their first wedding in an intimate 'practice' Las Vegas ceremony last month and then made things legal on Sunday May 15 in Santa Barbara, California.

But while the previous weddings had been lowkey, this weekend's nuptials and the days leading up to it were anything but.

On Friday, Kourtney dressed in a sheer red gown and Barker in all-black, were pictured looking glamorous as they made their way flanked by photographers to a restaurant in a small boat in Italy for a glitzy pre-wedding party.

The event, which was attended by their large family and friends, including Kris Jenner, Kim Kardashian and Megan Fox, was reportedly a no-expense-spared bash, which included a vast spread of delicious Michelin-star food and an endless flow of pricey champagne, cocktails and wine – although the tiny pasta portion sizes left a lot to be desired!

Earlier that day, the bride and her now-husband, were spotted sunbathing on a luxury multi-million-pound yacht believed to be owned and loaned to them for their entire wedding weekend by designers Dolce & Gabbana.

Kourtney was also seen on a series of pre-wedding outings in Italy with her family looking glamorous in various custom-designed Dolce & Gabbana outfits.

On one occasion, the mother of three was seen in a D&G black wedding mini-dress sporting a black veil and heels flanked by her stylishly dressed children.

The star's family also stepped out wearing Dolce & Gabbana in the run-up to the wedding.

Early last week, she also released black and white pictures of her wedding day in Santa Barbara 24 hours after the ceremony, wearing a white $1,825 (£1460) lace bustier frock with a pair of sheer gloves and matching veiL by the Italian designer duo.

'Till death do us part,' she captioned the snaps, one of which featured her straddling her new husband on top of a black convertible with 'just married' on the bumper.
