Kim Kardashian and Kendall Jenner are Fashion Week veterans at this stage, but it was their younger sister Kylie who stole the limelight last night.
The 18-year-old sat front row at the Alexander Wang show at New York's Pier 94, and even brought her boyfriend Tyga along for the occasion.
In standard Kylie style, she was sure to share some behind-the-scenes videos of the evening via Snapchat… including one very telling clip of herself and 25-year-old rapper Tyga.
Dancing with her man, Kylie looks into the camera before leaning in to kiss his top lip.
It doesn't look like the most romantic of smooches, given that Tyga's massive gold grill gets in the way, but there's no denying they're locking lips.
After posing for cameras in her black Alexander Wang AW15 black button down dress, Kylie made a quick change for a night out with her girls, Justine Skye and Anastasia Karanikolaou, known as Stassie.
Kylie posted a group selfie of the trio in her hotel room before they headed out, saying she was ready for a "much needed girls night."
Despite talk of it being a girls' night, Tyga was again present for the evening's main event, the Alexander Wang after party at Up & Down in the West Village.
Since turning 18, Kylie has been getting more and more open about her relationship with the rapper, although recently she tricked fans with a seriously sexy – but fake – video.
The intimate video shows Kylie locked in an embrace with someone who looks like Tyga, but in reality is one of Kylie's friends dressed as him.
