Kourtney Kardashian is definitely in the Halloween spirit.

The 37-year-old reality star threw a Halloween dinner on Monday night to kick off the Halloween season and she was definitely dressed to impress.

The oldest Kardashian sister channeled her dark side with an edgy costume that appeared to be a mix between a sexy vampire and Maleficent with her headpiece.

If you look closely you can see that Kardashian’s daughter Penelope got into the costume party spirit as well by dressing up as Frankenstein’s bride!

Kardashian rocked her stylish costume while celebrating a night of spooky fun with her best friends and their kids. Everyone dressed up for the occasion and proved you can still have a boo-tiful time even if you’re trying to watch the kiddies as you dine.

Kardashians party guests included the whole family’s makeup artist, Joyce Bonelli and fellow mom friend, Khadijah Haqq.

We also want to be Kourtney when we grow up — just look at how much fun she’s having while adulting. #LifeGoals.
