Kids Halloween costume ideas

There are so many options when it comes to Halloween costumes for kids, from scary skeletons to wicked witches and more.

While many people choose to make outfits as one of the many Halloween crafts for kids (opens in new tab) you can get stuck into over the autumn season, sometimes it's just easier to buy a costume online. As well as super easy, often-next-day delivery, there's always so much more choice when picking out a costume online. Of course traditional monster costumes are still the most popular designs but we reckon that newer costume ideas, inspired by kids' films and television shows, will be among the top choices this year.

So whether you're planning an all-out party with exciting Halloween food ideas (opens in new tab) or just setting up for an evening of Halloween movies for kids and adults (opens in new tab) on the sofa, these are the Halloween costumes for kids that we're loving this year.
