Where better to get Halloween costume ideas than from the celebrities who have been doing OTT fancy dress since way back when?
We're talking serious effort, year on year.
Heidi Klum is the leader of the pack when it comes to playing dress up, but Kim Kardashian, Paris Hilton and Beyoncé like to go all out on the costume front too.

10 Halloween fancy dress items you can find at home
The A-listers know how to get their freak on every October and they do zombie, Mexican corpse bride, Morticia Addams, skeleton, vampire and Miley Cyrus *very* well.
It's not all typical scare wear either - superheroes, Disney characters, anything from the 1980s and animals always rock up on the Halloween agenda. And yes, Kim Kardashian makes a pretty killer Catwoman.
While the outfit itself is a huge deal, it's the Halloween hair/wig and make up that can take your look to another level.
Heidi Klum's transformation from glossy, gorgeous model to grey-haired old lady complete with cane and varicose veins at her 14th Annual Halloween Party in NYC last year? Seriously impressive. As in, completely unrecognisable.
If you need some good old fashioned Halloween hacks (the kind you can find around the house) think: eyeliner, pots of brewed tea to stain clothes - shirts, skirts, sheets - and give them that antique-y look, saftety pins and tinned tomatoes.
