Reality stars Khloe, Kim and Kourtney Kardashian's clothing line beat stiff competition from the likes of Rihanna and Kate Moss to win the accolade at the Reveal Online Fashion Awards 2014, sponsored by Pro:Voke Touch of Silver.
Unfortunately, the Kardashian sisters weren't able to attend the glitzy event in London last month as they were busy prepping for Kim's wedding to Kanye West in Florence!
But the award reached them safe and sound in Los Angeles this week, with Khloe posting a picture of the glass trophy to Instagram.
And clearly she was rather thrilled by the honour!
"Wow! Our Kardashian Kollection at Lipsy London was voted 'Best Celeb Designer Collection' by Reveal Magazine in the UK!" she wrote.
"We are so honoured that our collection won, especially considering the amazing brands we were up against, including Rihanna's line for River Island and Kate Moss' line for Topshop.
"Thank you to everyone who voted, this is incredible!"
Khloe's Instagram post has been favourited more than 122,000 times so far, with thousands of fans sending their congratulations to the sisters on a "deserved" award.
The Reveal Online Fashion Awards 2014 were held at DSTRKT night club in London on 20 May.
