Goulding dressed up to attend a spooky bash at London restaurant West Thirty Six, alongside boyfriend Dougie Poynter.
The pop star's look wasn't quite a dead ringer for Kardashain's, as she mixed things up by adding a leather choker harness and large overcoat.

Goulding was still sporting her newly yellow locks, which she debuted on the red carpet at the MTV EMAs on Sunday 25 October.
But it might not be around for that much longer, as she recently shared a photo of her bright 'do on Instagram with the caption: "Felt like some sort of superhero for the night, but back to blonde now for me."
If you're a fan of Ellie and Kim's dress, you're in luck - the Paris Cut Pencil Dress is available to buy for £282.50 from the Atsuko Kudo website.
It seems more celebs than ever are looking to the Kardashians for fashion advice, as a red version of the dress was also recently spotted on Hollyoaks star Jennifer Metcalfe at the Inside Soap Awards.
Dougie Poynter chose not to dress up for the Halloween event, but looked dapper in an all-black ensemble and chic Fedora.
