Lauren Conrad is killing it in the Halloween costume game this year. First, she donned an awesome fawn costume along with a group of friends for a 鈥減arty animal鈥 themed dinner. #Squadgoals. And she鈥檚 back at it on Halloween day with a twinning costume so creepy, you鈥檒l have nightmares.

She and a pal dressed up as spooky little girls for a Halloween party in LA last night and she posted a snap of her look on Instagram. What is it exactly that鈥檚 so terrifying about haunted little children? We鈥檙e not sure if they鈥檙e zombie kids or ghost girls, but it鈥檚 creeptastic.

You can totally do your own, like our scary The Shining twins costume here, for an easy last minute costume. You just need matching dresses and makeup you likely already own (purpley shadows for under your eyes and a powder a shade or two too light for your face). In case you鈥檇 rather go pick something up at the store, since the haunting hour is upon us, here鈥檚 what you鈥檒l need. Also, don鈥檛 forget the face paint!

1. A babydoll dress with a Peter Pan-collar: First and foremost, it鈥檚 all about the dress. There鈥檚 nothing that will help you nail the ghostly kid look better than a babydoll dress with a Peter Pan-collar, like this Urban聽Renewal Baby Doll ($59).

2. A sweet + spooky hair bow: Something about the juxtaposition of sweet and scary somehow enhances the scary (like adding salt to your cookies makes the sugar even more pronounced). You can score one of these hair bows just about anywhere, but a good option is this Forever 21 Classic Bow Barrette ($3).

3. White knee-high stockings: The knee high stockings are definitely a must. It鈥檚 great if you already have a pair laying around, but in case you don鈥檛, check out these DKNY Opaque Microfiber Knee Highs ($8) to really make your look a standout.

4. Mary Janes: Here, you have lots of options. You can go with flats or heels, patent or suede, black or maroon. Go crazy! We picked these Vince Camuto Joshlynn Mary Janes ($139) because they鈥檙e perfect for a party but chic enough to wear on all the other days of the year.

5. An adorable stuffed teddy: The teddy is definitely the finishing touch 鈥 though you could go with any stuffed toy you please. Maybe you already have an old huggable stuffed animal that will round up this outfit, or you could spring for this plush bear with a bow ($15) to match your outfit.
