The Invasion of Privacy rapper embraced the spirit of the holiday by paying tribute to one of the sexiest criminals in Batman's rogues gallery: Poison Ivy.
Rocking thigh-high jade green boots, a greenery-adorned bustier, ivy leaf-eyebrows and impossibly long, ruby red hair that trailed behind her, Cardi was the perfect embodiment of Uma Thruman's take on the Poison Ivy persona from 1997's Batman & Robin.
The 27-year-old GRAMMY-winning rapper shared two pics of the impressive costume, the first of which showed her laying on her side in a teal room, which she captioned, "MONEY IVY ???"
This is the second Halloween costume Cardi has rocked this year, after dressing up as a sexy nurse over the weekend for her performance with husband Offset at Power 105.1's Powerhouse 2019 concert in New Jersey.
Cardi took to Instagram to share a snapshot of the sultry outfit, which coincidentally also featured a super long, bright red wig.
