The DJ and TV personality, 32, attended the Diane Von Furstenberg Journey of A Dress 40th Anniversary Party in Los Angeles last night (10 January) and naturally had to wear a DVF dress!
A big fan of the Belgium designer, Paris wore a limited edition pop wrap dress with Andy Warhol's iconic blue, red and yellow flowers over DVF's signature chain link print.
The pretty silk frock shows exactly why the designer's wrap dresses merit their own anniversary party 40 years after Diane first designed the style.
During the night, Paris couldn't hide her enthusiasm as she took to her Twitter account to express her respect for the designer.
She wrote: "I heart @DVF. She's a style icon, one of my favourite designers & such a classic beauty."
Later she added: "Loving @DVF's #JourneyOfADress exhibition! So many beautiful dresses! Incredible!"
She also couldn't resist sharing a picture of herself and sister Nicky which was displayed as part of the exhibition...
Alongside the archive shot of the siblings both in DVF wrap dresses, Paris tweeted: "Love all these amazing iconic photos from @DVF's exhibition!"
Whitney Port, Jesse Metcalfe, Bella Thorne and Joe Jonas were also among the stars celebrating the famous dress.
