See What Karli Kloss, Demi Lovato, Rita Ora, Jennifer Garner And More Wore For Halloween

When Halloween falls mid-week like it does this year, people start dressing up well in advance for weekend parties beforehand. Celebrities do the same thing, and have been partying it up since last week. Here are our favourite outfits for the spookiest day of the year so far. 

Model Karli Kloss went classic in this ensemble, channeling Marilyn Monroe from Some Like It Hot. She does a pretty good job of it too, and the costume is one of our favourites we’ve seen so far.

Kristen Bell admitted that it wasn’t her idea to go as Elsa from Frozen and that she was talked into it by her daughter, but we can pretty much tell that from the look on her face. Still, she does the role justice, although the look might be because she played Anna in the film.

Rita Ora is simply poison, as in Batman’s foe Poison Ivy. Perhaps if they have the villain in a future movie Ora can be cast.

We’re not sure what Adele was dressed up as, but it looks like she was having a lot of fun doing it. The singer had been on a bit of a break from social media, but when this popped up her fans certainly took notice.

Demi Lovato paid tribute to singer Selena in this get-up on Snapchat, and we feel she did the costume justice.

Jennifer Garner shows us that costumes don’t have to be a tribute, or even make a lot of sense, but as long as you look cute and enjoy yourself, they don’t have to. Such as this cute little cat-of-some-sort costume.

And finally, Gwyneth Paltrow wears a costume only she could wear. Her character in Seven ended up with her head in a box, and here she revisits that classic look.
