Don't kiss these ladies!
Former "90210" costars Shenae Grimes and Jessica Lowndes had the same idea for Halloween this year -- and both stepped out in very different Poison Ivy costumes.
Shenae hit the carpet on Tuesday night at Bootsy Bellows for the 3rd Annual Midori Green Halloween, sporting a thematically-appropriate getup. Her take was clearly inspired by Uma Thurman's version of the villainess from "Batman & Robin."
Over the weekend, Lowndes showed off her interpretation of the look, modifying the costume so she could show off her legs and cleavage by wearing a mini instead.
So, who did it better? Our vote is for Gimes for her commitment to the character. But what do you think? Vote below!
Shenae wasn't the only one who attended the party last night. Check out the gallery above to see Christina Milian and Jenna Ushkowitz's costumes, plus see some of the best looks from this year ... so far.
