If you're having trouble working out what to wear this year, find some fancy dress inspiration from these eight classic clips, and prepare to get your fright on...
1. The Sanderson Sisters in Hocus Pocus
Hocus Pocus has to be the best Halloween movie of all time. Rope in two friends and recreate the full trio.
2. Baby from Dirty Dancing
All you need is a brown curly wig, a white sundress, and a pale blue cardie. Plus a watermelon, obviously.
3. Cruella De Vil in 101 Dalmatians
Every girl needs to dress up as Cruella once in her life. Fact.
4. Elle in Legally Blonde
A long blonde wig, an all-pink outfit and a toy chihuahua on a leash... Easy peasy.
5. Wilma in The Flinstones
A red wig, giant pearls and white shift dress equals fancy dress perfection. And going as Betty wouldn't be a bad shout either.
6. Sandy in Grease
All you'll need is a curly blonde wig, some skintight black trousers and a pair of red mules. Simple but effective.
7. Morticia from the Addams Family
A true Halloween classic.
8. Cady in Mean Girls
You could follow the Mean Girls slut rule and just wear 'lingerie and some form of animal ears', but we think Cady's genius ex-wife costume might be the way to go.
