One of my favorite parts of Halloween is getting creative with costumes—especially when it comes to my toddlers. Buying pre-made costumes can get pricey fast, but with a little DIY magic, you can create something unique, budget-friendly, and absolutely adorable.

Best DIY Toddler Halloween Costumes

Here are some of my best DIY toddler Halloween costumes I’ve made over the years, complete with step-by-step instructions and a few fun stories along the way.

Peter Pan & Tinker Bell (Plus Captain Hook!)

When my little one was a baby, I decided to make him a tiny Peter Pan costume, and it ended up being one of the easiest (and cheapest!) projects I’ve ever done.

How I made the Peter Pan costume:

  • Start with a green toddler sweatshirt. Cut zigzags along the sleeves and hem.
  • Add green tights for the pants.
  • Tie a brown ribbon around the waist for a belt.
  • For the hat, I found a simple origami paper hat template online, then traced it onto green felt. I hot glued the pieces together and added a red felt feather.

Tinker Bell (my costume):

  • Grab a green dress and cut the edges in a jagged, pixie-style shape.
  • I painted an old pair of flats with green acrylic paint and hot glued cotton balls on top for the iconic Tinker Bell look.

Captain Hook (for dad):

  • Use a long-sleeve red shirt and cut it open down the middle like a jacket.
  • Add gold ribbon trim for details.
  • Pair it with black pants, a hat (or DIY one), and of course a toy hook hand.

This trio made the cutest family costume set—perfect if you’re looking for a group theme!

Baby Bear (Upgraded Store-Bought Costume)

Sometimes, the easiest DIY costume hack is taking a store-bought costume and making it better. My son had a little lion costume, but the mane was thin and floppy. It didn’t look very “wow,” so I decided to fix it.

How I elevated it:

  • I bought a strip of faux fur fabric from Hobby Lobby (you can also find it on Amazon).
  • Hot-glued the extra fur onto the mane to make it look fuller and fluffier.

This quick upgrade instantly made the costume look way higher quality—like something you’d buy from a boutique instead of a discount rack. You could do the same thing with almost any animal costume—think adding buttons, fur trim, patches, or even sparkles. A little DIY flare can completely change the vibe!

Little Lamb (Farm Theme Perfection)

For a newborn, I wanted something cozy and sweet, so I turned a simple black hoodie into an adorable lamb costume. It was perfect for a family “Old MacDonald” theme.

How I made it:

  • Start with a black zip-up hoodie.
  • Cut small white felt ovals, pinch them at the base, and hot glue them to the hood for ears.
  • For the fleece body, hot glue cotton balls or felt “puffs” onto the front of the hoodie. (Pro tip: keep them only on the front so your baby can still fit comfortably in their car seat.)

It was simple, cute, and super cozy for a chilly October night.

Cruella Deville & Dalmatians

This one might be my all-time favorite DIY family costume. It’s bold, fun, and surprisingly low effort.

How I did Cruella:

  • Curl your hair, then part it down the middle. Use white hair spray on one side and black hair spray on the other. Pin it up messily for that dramatic Cruella look.
  • Wear black leggings and a black shirt.
  • Add a fur coat (Amazon or thrift store), red gloves, and chunky jewelry.

For the dalmatians (kids, husband, or even your dog!)

  • Start with a white hoodie or onesie.
  • Cut black felt spots in random sizes and hot glue them onto the hoodie.
  • Make floppy ears out of felt and attach them to the hood.

One year, I even painted my husband’s face to look like a dalmatian—people loved it! This set always got us tons of compliments, and it’s such a great option if you want a “minimal effort for the boys, maximum fun for the girls” type of family costume.

Final Thoughts

DIY toddler Halloween costumes don’t have to be complicated or expensive. With a little creativity (and a hot glue gun), you can make costumes that are unique, comfortable, and way cuter than store-bought versions. Whether you’re pulling together a whole family theme or just dressing up your toddler for trick-or-treating, these ideas are easy wins.

And the best part? You’ll always have sweet memories of the costumes you created yourself.
