Alongside her boyfriend and actor Chris Zylka, the 36-year-old wore a feathered white skirt and corset top with a rabbit face on it for the annual Treats! magazine party on Tuesday night.
To complete the ensemble, the lifestyle brand entrepreneur, who has a line of footwear, fragrances and accessories, wore a pink and white bunny ear headband with faux fur and pink sequins, a bejeweled white neckband and white leather riding gloves.
On her feet, Hilton had on a pair of reflective sky-high silver Christian Louboutin heels — the iconic red sole peeking out in photographs. The reality TV star and hotel heiress has been a longtime fan of Halloween — she dressed up as Little Red Riding Hood, a sexy airplane pilot and a sexy sailor in past years.
Staying by Hilton’s side throughout the night, Zylka went as Pac-Man with a black hoodie, track pants and a bright yellow face mask. Popular DJ Diplo donned a bright orange jacket with a skeleton bodysuit underneath, and rapper Chanel West Coast was a bombshell cowgirl in red boots.
Tara Reid, Monica Sims and Tamie Sheffield were some of the other famous faces photographed at the bash, which was sponsored by Absolut Elyx, Perrier-Jouet, Avion and Rolls-Royce.
