What to Look for When Buying Halloween Costumes for Babies

Trendiness

Parents tend to fall on a spectrum when it comes to trendy things for their kids. Some parents have a “the trendier the better” mentality, some want their kids to stand out from the trends, and others fall somewhere in between. If you’re looking for something really trendy, consider a character from a recent well-loved movie or a popular object in costume form (like an avocado).

For the caregivers who fall in the middle, go with something timeless like a Jack-O-Lantern or a character like Mickey Mouse. As for the parents who like something totally different, go with an animal or character that wouldn’t normally be so cute if it weren’t for your baby, like a skunk or a spooky character from a movie. 

Comfort

Unless you want to spend Halloween soothing a fussy baby, you’ll want to make sure the costume you buy is comfortable. Make sure all of the fabric touching your baby’s skin is soft, not scratchy or rough, won’t make them too warm or cold, and doesn’t limit movement at all. 

If it is typically chilly in your part of the world on Halloween, consider sizing up, so your little one has plenty of room for you to comfortably add layers underneath their costume. This way they'll but warm and toasty without imposing on their spooky look.

Sizing

Baby clothing sizing is rarely consistent across brands, and the same is true across costume brands. Costumes are typically sized in either two, three, or six-month increments, and it’s especially important to get sizing right for the littlest babies who aren’t able to control their heads or rollover as well as for older babies who are cruising or walking.

For the youngest babies, you’ll want to avoid costumes designed to fit babies 0-6 months, as they will likely be much too large. While a slightly loose costume on an older baby might be okay, it’s important to pay attention to the length so that they don’t trip and fall while walking.
