Gotham's Smallest Guardian

Even the smallest heroes answer the call of the night. Before he can walk, he can wear the cape — and Gotham City has never had a protector quite this adorable.

The Dark Knight's Signature Look, Tiny Edition

This infant Batman costume captures the iconic look of DC's legendary Caped Crusader in a size built for your little one. The classic black and grey color scheme is unmistakably Batman.

The attached cape completes the heroic silhouette, making even the smallest members of your trick-or-treating crew look ready to defend the city.

Comfort Fit for Tiny Crime Fighters

Designed with infants in mind, this costume is crafted to keep babies comfortable throughout the night's adventures. Soft materials ensure no fussing — just pure superhero charm.

Easy to put on and take off, this costume is a lifesaver for parents wrangling a wiggly little Batman between candy stops and photo ops.

A Halloween Memory Worth Keeping

The first Halloween is one for the scrapbook. Dressing your infant as the World's Greatest Detective is a moment family members will talk about for years to come.

Pair with a Wonder Woman or Superman costume for siblings, and the whole Justice League is ready for the neighborhood.

Questions & Answers

Q: Is there a size chart? My child is 26 lbs and will be 21 months old. (1 Answer)

Monster Responds...
At 26 lbs and 21 months, your little one has grown past the largest size we carry for this costume, which goes up to 12/18 months. Checking our size chart before ordering is always the best move, and in this case it looks like a different style in a toddler size range would be a better fit for your Batman fan.

Q: Size chart? (1 Answer)
Asked by Taylor | August 30, 2026
Monster Responds...
For this infant Batman costume, sizing is based on your baby's age: 0/3 months, 3/6 months, 6/9 months, 9/12 months, and 12/18 months. When your little one is between sizes, we recommend sizing up for the most comfortable fit.
