In her next outfit, Kardashian sizzled in a dark green sequined bikini and pulled her blonde wig up in a ponytail.
The KKW Beauty founder took some photos in a swimming pool while on a pink raft with a friend who wore a blue bikini.
Kardashian went all out for her Halloween costume, even creating a parody of Elle Woods' admissions tape for Harvard Law School and sharing it to Instagram.
Kylie Jenner also dressed up in several costumes for Halloween this year, including Disney's The Little Mermaid.
The billionaire mogul shared several photos of herself in a green sequin skirt and a purple seashell bustier with white fishnet sleeves.
Jenner also wore a long red wig, like the character from the cartoon film and appeared to be wearing contacts.

The 22-year-old also unveiled her V Magazine cover as part of another Halloween Costume.
Jenner dressed up as Marilyn Monroe in Gentlemen Prefer Blondes, wearing a pink dress (like the Old Hollywood icon did in the film).
The Kylie Cosmetics founder proved that diamonds really are a girl's best friend as she adorned herself in various pieces of jewellery.
Jenner shared several photos of the photoshoot on her Instagram, including one of herself reenacting Monroe's classic "Diamonds Are A Girl's Best Friend" performance.
It appears reenactments are the theme for the Keeping Up With the Kardashians star this year.
Last weekend, Jenner - who shares daughter Stormi Webster with ex-boyfriend Travis Scott - dressed up as Madonna (specifically from her performance at the 2003 MTV Video Music Awards when she shared a kiss with Britney Spears and Christina Aguilera onstage).
Jenner even shared a kiss with her best friend Stassie (who was dressed as Britney Spears).
Once again, the stars of Keeping Up With The Kardashians have won Halloween!
