The 17-year-old smouldered on the red carpet, as she sported new pastel blue locks and a plunging white jumpsuit.
Accessorising with plenty of gold and silver jewellery, Kylie channelled a distinctly 70s vibe through her outfit - updated with her on-trend mermaid hair.
The event in West Hollywood was held to promote her line of hair extensions with Bellami.
Kylie is the face of the clip in extensions, which retail at around $249 for a box of 20.
The 17-year-old star also showed off her impressive cleavage on the red carpet, which has had many speculating that she has gone under the knife in recent months.
Responding to the allegations a few weeks ago, Kylie said: ‘To whoever thinks I had breast implants, there’s a whole lot of tape in here holding these up.’
What do you think of Kylie's new hair? Would you try the trend?
