The Kardashian sibling is often seen sporting denim cut-offs and rock chick vest tops, but on Wednesday afternoon (2 October) she swapped her laid back wardrobe for an outfit that was far more elegant and grown-up.
She wore a pastel coloured coat with a waterfall style hem and structured shoulders.
We can't help but wonder whether she has been taking a few fashion tips from her older sister Kim, who has been seen in a pretty pale pink coat in Paris this week.
Kylie, 16, buttoned the coat all the way up, so that her clothing underneath couldn't be seen. She also made an impression with her fancy footwear, by ditching her usual biker boots and wedge trainers for a pair of black shoes with a cage design going up to the knee.
Or maybe they are actually a pair of knee-length fishnet tights? We can't quite tell!
Either way, it's fair to say that Kylie looks glam beyond her teenage years in this get-up and is beginning to give her older sisters a run for their money in the style stakes.
The reality TV star also flashed her new blue locks, which sister Khloe dyed for her earlier this week.
However, the blue isn't as drastic as we had thought (or hoped) it would be, as it looks like only a few strands of hair have been coloured.
Kylie was seen keeping Khloe company yesterday on a shopping trip in LA. The two girls were joined by mum Kris Jenner and were pictured getting some goodies from clothing store Kitson.
