Kourtney, Kim and Khloe Kardashian have transformed over the years.
And their half-sisters Kendall and Kylie Jenner are almost unrecognisable.
Kim
The middle Kardashian sister first became known for being best friends with Paris Hilton - and for her love of figure-hugging satin.
She's one of the biggest fashion icons in the world now, but Kim used to have very different style.
Mrs Kardashian-West would never step foot on the red carpet in something so casual.
Hanging out with mother Kris Jenner, Kim occasionally got it right pre-2013.
But this outfit - worn at the 2013 Met Gala while pregnant with daughter North - is something that was heavily criticised.
Two years later, she more than made up for the fashion faux pas.
Now her new looks regularly break the internet.
Khloe
She's one of the most glamorous sisters now, but just a few years ago Khloe looked very different.
Her red carpet style was casual and laid back.
She's always been a fan of showing off her amazing figure.
Big hair and sparkles during her time as a presenter of The X Factor USA.
These days her fashion choices are a lot more risque.
And there's no denying that, in 2016, she looks incredible.
Kylie
One of the biggest Kardashian/Jenner transformations comes from youngest sister Kylie.
Looking cute rather than chic on the red carpet.
Finding her fashion feet.
These days Kylie never gets it wrong.
And has become a style icon in her own right.
