What do you do to celebrate your 17th birthday when you're Kylie Jenner? Head to the 2014 Teen Choice Awards with your two super-famous siblings, of course.
Kim Kardashian and Kendall Jenner joined Kylie on the blue carpet to create one very stylish sister act.
Birthday girl Kylie opted for a gold printed wrap skirt and black crop top, while Kim also opted for a clingy zebra-print skirt, which she paired with a funky long-sleeved leather crop top.
Kendall took something of a different approach and looked elegant yet sexy in an all-white ensemble consisting of wide-leg trousers with sheer cutouts, and a high-necked top.
And it turned out to be a brilliant birthday for Kylie, as the sisters picked up the Choice Reality Show award for Keeping Up With Kardashians.
Kendall was also nominated for Choice Female Hottie but missed out to Selena Gomez.
To celebrate Kylie's 17th, Kim posted a series of pictures of her sister when she was young to her Instagram page and wrote: "To my baby sister on her 17th birthday...I was 17 when you were born and every day you have brought me such joy! I love living with you! I love how strong you are, funny and just so stylish!!!! I found a bunch of selfies you took on my camera when you were maybe 9 years old & for your birthday I will post them all! Love you so much!"
And, of course, there were a number of selfies posted en route to the Teen Choice Awards. Kim captioned one: "Now time to celebrate @kyliejenner 'a birthday!"
She also let us in on her style secrets for the night, posting a picture of her posing at the bash, writing: "Teen Choice Awards look- Balmain top & skirt. Balenciaga heels."
