Seeing your little one in a costume is the sweetest moment on that first Halloween. But the price tags on those darling baby Halloween costumes can be scary, especially when your baby may not even be big enough to trick or treat or play at a Halloween party.
Don’t fret: there are plenty of ways to save money on Halloween costumes for your newborn. You just have to think outside the box and consider what clothes your kid already has (bunny ears and a tail can go a long way with an all-white outfit) and from there, be smart about how and where you shop.
We researched popular baby Halloween costumes you can get for cheap, plus sprinkled in some ideas on how to improvise when you’re on a budget. A quick tip: we’ve been watching the prices fluctuate weeks leading up to Halloween. You can save up to 30% on closeout deals now, but some costume prices have soared during the final days before the holiday. But, you know we’ll only share the deals that’ll help you save.

How to Find Cheap Baby Halloween Costumes

1. Go Through Your Closet
The best place to start looking for baby Halloween costumes ideas is at home, where you can source your costume not just for cheap but for free. Solid-colored onesies or pajamas make a great starting point for a costume where all you need to add is a headpiece or a few accessories. Dresses and colorful hair chalk can be the start of a princess or fairy costume. Animal print rompers lend themselves well to creating a budget-friendly tiger or zebra costume.
2. Check Facebook Marketplace
Score big savings when you swoop in first on a Facebook Marketplace ad listing costumes of your kid’s favorite characters or animals. Parents like to unload not just costumes that kids grow out of but also the extra costumes their kids own from the multiple Halloween parties they attend leading up to the event.
You’ll sometimes find that parents are often willing to sell items for up to 90% off what they originally paid. As always with Facebook Marketplace, we recommend meeting in public places for pickup and only paying when once you’ve seen the item in person.
3. Shop Smart
Overall, we found that Target and Party City were the top spots for inexpensive accessories that you could add to finish a homemade costume. Walmart and Amazon were the best places to find rompers or full ensembles that double as cheap Halloween costumes (and quickly too). BuyBuy Baby has great options for licensed characters, and their My Rewards program — where they reward you with funds for qualifying purchases — makes the deals even better.
- Take advantage of rewards programs. Use your Target RedCard to save an additional 5% on qualifying purchases. With BuyBuy Baby My Rewards, members can earn 10 points per dollar for each eligible purchase made online or at the store that they can use for future purchases.
- Cross-check the same costume at various retailers. You’ll notice that there isn’t just one version of a Baby Yoda costume out there. We found that Disney’s version of Baby Yoda costs about three times as much as BuyBuy Baby’s hat and bootie set.
- Size up. If you purchase a costume one size bigger, you might be able to get two years’ use out of it or even pass it on to a younger sibling. You’ll also often find that kids like to throw on the same costume to play dress-up or to get in the mode for storytime.
Whether you’re looking for a $5 headpiece to round out your baby’s DIY Halloween costume or you need a head-to-toe costume, we have dozens of ideas to help you save money this Halloween. Let’s take a look!
