Life is better over the sea, because that’s where Kylie Jenner could be found serving looks in her Ariel costume! The Keeping Up with the Kardashians star was a knockout in her seashell bra and thigh-high slit skirt (AKA mermaid tail), inspired by a Disney classic — The Little Mermaid. Keeping to theme, Kylie even rocked an extremely cropped fishnet top and fish purse (yes, that’s Flounder, Ariel’s finned sidekick).

Kylie’s Ariel costume was just one of the many outfits that took Halloween’s sexy crown for 2019. Blac Chyna incorporated a giant skull into her costume and still made it seductive, Lisa Rinna dressed as another celebrity who happens to be the master of sex appeal, and Paris Hilton had us screaming ‘That’s hot!’ in her sailor dress. This Halloween produced many sexy costumes to take notes from, considering that the holiday basically spanned a week. Now, click through the rest of HollywoodLife’s gallery and get ready to ‘ooo’ and ‘ahh.’
