20 Kids’ Halloween Costumes Available at Walmart for $30 or Less

We are getting closer and closer to the spookiest time of year! Although Halloween is one of the less expensive holidays, the one thing we always have to rush out and purchase (often last-minute) is a costume. And depending on how many little ones a mom has in her gang, she may have to buy several. Halloween costumes are tons of fun, but between the outfit, accessories, and sometimes makeup and wigs, it can easily add up. Luckily, Walmart has some great kids' costume options that are totally affordable and on trend with the year's biggest characters and themes for all ages. 

Whether a kid was really into Jurassic World, The Incredibles, Power Rangers, or Black Panther, there are costumes for almost every major movie that released in the last year. Walmart also has some of the more traditional Halloween costumes, such as a vampire, zombie, fairy, and hippie. It even has some career-focused ones. If someone's kid is set on becoming a doctor, a police officer, or a firefighter when they grow up, then they might really enjoy dressing up as one this Halloween. And then there are the ever popular Harry Potter costumes, Disney's Descendants characters, and even the classic My Little Pony. There are plenty more than the ones on this list, but here are 20 Walmart kids' costumes that are all under $30. Not only are these good for the budget, but kids will love them! No matter what a mom's Halloween needs are, Walmart likely has it!
