The teenagers were among the guests in Florence, Italy when Kim exchanged vows with rapper Kanye West on 24 May.
"It was amazing, it really was," said Kylie, during an appearance on The Tonight Show starring Jimmy Fallon.
Kendall added of the beautiful photo of Kim and Kanye kissing at the altar: "Kanye surprised Kim with a wall of flowers on Mother's Day and then a huge one for their wedding. Seriously, how do you top that?!"
While the celebrity couple's nuptials took place at the Fort Belvedere in Florence, there was a week of pre-wedding celebrations held in Paris, France, including a lavish reception at the iconic Palace of Versailles.
Kylie said her highlight of the whole wedding experience had been seeing Lana Del Rey performing at Versailles. "She's one of my favourite artists. She's beautiful and amazing."
Kanye arranged for Lana to perform as she's one of Kim's favourite artists. Lana's song 'Young and Beautiful' was playing in the background when Kanye proposed to Kim in October 2013.
Meanwhile, Kendall said her favourite part of the wedding was watching the fireworks going off at Versailles at the end of the night. "It was just beautiful and really romantic."
Kim and Kanye flew their guests from Paris to Florence for the actual wedding. Afterwards, the newlyweds jetted to Ireland for their honeymoon, before continuing on to Czech Republic to attend Kanye's stylist's wedding.
The couple returned to the US this week but are already separated, with Kim in LA looking after their eleven-month-old daughter North, and Kanye over in New York.
