Kourtney Kardashian rocked an all-denim look as she partied the night away celebrating her sister Khloe's big birthday – and we're obsessed with her take on the trend.
The whole Kardashian clan embraced the denim theme. Birthday girl Khloe opted for a corset-style top with wide-leg jeans and a denim cowboy hat.
However, older sister Kourtney, 45, went for a more understated look, but certainly no less impressive.

Kourtney paired the large shirt with some sheer black tights and chic black court heels.
Her hair was styled in her go-to wet look finish, with her makeup consisting of ultimate glam including dark eyeliner with a pale pink lip.
The reality star also included a nod to her husband with a gothic-style silver chain around her neck reading 'Mrs Barker'.
At the party, Kourtney even managed to squeeze in some branding with her 'Lemme' vitamin and supplement capsule line being handed out to guests.

Kourtney often opts for a grunge-style look, particularly when out and about with her rockstar husband, who she has only just begun living with under the same roof.
In an episode of their Hulu show, The Kardashians, the 45-year-old, who shares Mason, 14, Penelope, 11, and Reign, nine, with her ex Scott Disick, explained how their blended family meant they were living in separate abodes.

Travis, 48, is also a dad to Landon, 21, Alabama, 19, and his stepdaughter Atiana De Le Hoya, 25, from his previous marriage to Shanna Moakler.
Khloe's epic birthday party
The birthday party for Khloe's 40th looked to be a spectacular affair.
The majority of the Kardashian-Jenner crew were in attendance including Kim Kardashian, Kylie Jenner, Khloe and Kourtney, as well as matriarch Kris Jenner. Kendall, however, did not appear to be present in the photos.

Elsewhere, there was an electric bucking bronco to entertain guests. Videos shared on social media showed Kylie, 26, and her best friend Stassie Karanikolaou riding the bucking bronco while laughing together.
