We've got the top best friend Halloween costumes to order online (or to DIY at home) this year.

RELATED: 21 Powerful Female Superheroes To Dress Up As & The Best Women's Superhero Costume Ideas For Halloween

Between the fun of dressing up, the plethora of free candy, and the spooky feel of the occasion — Halloween one of the best holidays of the year!

Whether you're going to a fun Halloween party, staying in for a scary movie marathon, heading to a creepily decorated haunted house, or simply taking the kids trick or treating (or staying home to hand out candy) — you should always get in the spirit of things and dress up for Halloween with your friends!

Planning the perfect matching costume with your friends takes time. Especially if you and your bestie have decided to turn it into a fun DIY project that you’ll do together.

But they don’t have to. Sometimes only a little effort makes the best (and cutest) costumes.

A lot of the costumes that made our list are quite easy to just throw together real quick (you may even have everything you need in the house) if you don't want to buy it online and wait for it to ship. There are also options for ready-to-wear costumes if you aren't keen on DIY projects!

So, without further ado, let’s do the monster mash into these top matching best friend Halloween costume ideas!
