If you and your bestie find yourselves headed to Halloween party on the fly without a costume, these last minute best friend Halloween 2017 costume ideas are easy to throw together. Seriously, with just a few items from your closet, or an overnight order from Amazon, no one will know that you haven't spent months planning your epic monster's ball outfit. A little creative thinking can help you quickly create a costume that honors your favorite musician, gives a nod to an epic scare pair, throws shade at social media, or has you going down a nostalgic rabbit hole.

Halloween is the one night each year where it's totally acceptable to wear something you wouldn't be able to any other day. I mean, you should be able to dress how you want every single day, but some employers might not appreciate you and your BFFs' Lady Gaga and Beyoncé "Telephone" costumes at the weekly staff meeting, especially if your BFF doesn't work there too. But, hey, that's OK because you and your bestie can take advantage of Halloween 2017 to rock some wild best friend costume ideas that everyone will definitely appreciate.

Having a partner in crime to pair up with Halloween is what makes the holiday so much fun. If you and your bestie need a last minute costume idea for Halloween 2017, consider going as one of these dynamic duos.
