12 Halloween Costume Ideas for Kids – Easy DIY and Ready-to-Buy Options

Halloween is just around the corner, and if you have little ones at home, you probably already hear the daily question: “Mom, what can I dress up as this year?”

I’ll be honest: I absolutely love Halloween. No other holiday makes me as excited! For me, it’s pure joy and fun, and I adore the positive energy it brings. It’s that time of year when we start looking for inspiration—costumes for ourselves, our kids, even pets, and ways to decorate the house.

In this post, I want to share my favorite Halloween costume ideas for kids. These are perfect for twins, siblings close in age, or just brothers and sisters. As a mom of twins, I know how tricky costumes can be—you naturally want to dress them in matching outfits. But here’s a little reminder: listen to your kids, too. Sometimes children who already share everything don’t want to match. And that’s totally okay.

Still, let’s be honest—kids love dressing up. And Halloween is the best chance to play together, to get creative, and maybe discover their spooky side. Below you’ll find my top picks for costumes for little ones (ages 2–5). Each idea includes simple DIY tips you can pull off with clothes you already have, plus Amazon links for quick “add to cart” moments if you’re short on time.

Below, you’ll find ideas for creating full costumes at home using stuff you already have—super creative and budget-friendly! But if DIY isn’t your thing, you’re a busy mom with zero time for yourself, or you just need a quick fix, check out the links I’ve shared, guilt-free. I’m here to make your life easier, not to judge! 😊

Pop Culture Inspired Costumes

1 Joker and Harley Quinn

This one’s my favorite, so let’s start strong. Mini versions of Joker and Harley Quinn? Nobody will wonder who your kids are supposed to be. These iconic characters are instantly recognizable, and they’re hilarious in a pint-sized version. You can create the looks with clothes you already own or mix in a few affordable Amazon finds.



Joker DIY:

Grab an old button-down shirt (too big is fine—it adds to the quirky vibe) and a jacket from Dad’s closet. For the iconic green hair, use washable markers to color a paper plate green, cut it into a messy “wig” shape, and pin it to their hair. Face paint is key: dab on some white face paint (mix flour and water for a homemade version) and add red lipstick from your makeup bag. For a final touch, draw a fake scar with an eyeliner pencil. If the shirt’s too long, cut the hem into jagged strips with scissors and fray the edges by pulling out threads with your fingers for that chaotic Joker look.

Amazon picks:



- here you will have to trim the wig a bit




Harley Quinn DIY:

Start with an oversized T-shirt from your laundry pile—white or light-colored works best. Use red and blue markers to draw bold patterns or dip-dye it with food coloring (mix with water and soak sections of the shirt). For pigtails, tie hair with colorful ribbons or yarn scraps. Make a tutu by knotting strips of old red or blue fabric around an elastic band (like from an old pair of pants). For torn tights, take old leggings, snip small holes at the knees, and gently pull threads to create a frayed effect. A dab of red lipstick and a drawn-on heart under the eye seals the deal.

2 Wednesday and Pugsley Addams




Thanks to Netflix’s Wednesday, this gothic queen is ruling Halloween 2025, and her brother Pugsley makes the perfect sidekick. I’ll be honest—sometimes I look at my daughter’s deadpan stare and think she’s already channeling Wednesday without a costume. Her “spooky” face could scare anyone at the Halloween party!

Wednesday DIY:

Dig out an old black dress or a long black T-shirt from your kid’s wardrobe (an oversized one gives that Addams Family vibe). For the iconic Peter Pan collar, cut a white paper plate into a collar shape and pin it to the dress. Braid their hair tightly—two braids are non-negotiable. If you want to add a gothic touch, use a black marker to draw “veins” on their hands for a creepy effect. An old belt or scarf tied around the waist can cinch the dress for a more fitted look. Pro tip: practice the Wednesday stare with your kid in the mirror—it’s half the costume!

Amazon picks:





Pugsley DIY:

Find a black-and-white striped T-shirt (or paint stripes on a plain white one with a black marker). Pair it with dark shorts or pants—cut the hems to make them look worn and fray the edges with your fingers. Add suspenders made from ribbon or elastic strips from old clothes. For a fun touch, stuff the shirt with a small pillow to give Pugsley that classic “chubby” Addams look. My twins love this because it makes them giggle when they waddle around.

Amazon picks:


3 Batman and Catwoman



A classic that never gets old. Growing up in the ‘90s, I watched Batman reruns religiously, so seeing my kids as Batman and Catwoman feels like passing the torch. Kids love superheroes, and this duo is a guaranteed hit.

Batman DIY:

Use an all-black outfit—hoodie, leggings, or sweatpants. For the bat symbol, cut a bat shape from yellow construction paper or an old yellow T-shirt and glue it to the chest. Make a mask by cutting eye holes in a black sock or beanie, then add bat ears by taping on triangles cut from black cardboard. For a cape, tie an old black pillowcase around their shoulders. If the pants are too long, snip the bottoms into jagged edges for a rugged superhero look.

Amazon picks:





Catwoman DIY:

Start with black leggings and a black shirt. Make cat ears by twisting pipe cleaners (or folded paper) into triangles and attaching them to a headband or hair clips. For a tail, stuff an old black sock with cotton balls or fabric scraps and pin it to the pants. Add whiskers with eyeliner or face paint (mix cornstarch and water for a DIY version). My daughter loves swishing her tail around like she’s prowling Gotham!

Cat Costume




4 Chucky and Creepy Doll



This creepy combo is perfect for siblings who want to stand out. My daughter’s mischievous grin already screams “Chucky’s creepy doll,” so this one feels personal. Nobody will forget this duo at the Halloween party.

Chucky DIY:

Use old denim overalls (or cut up old jeans to make them look oversized). Pair with a colorful striped T-shirt—draw stripes with markers if you don’t have one. For the red hair, twist orange yarn or pipe cleaners into a messy “wig” and pin it to their hair. Add scars with eyeliner or face paint (draw jagged lines on the cheeks). For extra flair, cut the overalls’ knees and fray the edges by pulling threads—Chucky’s supposed to look a bit unhinged!

Amazon picks:




Creepy Doll DIY:

Grab an old dress (even one they’ve outgrown) and make it “vintage” by tearing the hem slightly. For the porcelain doll effect, mix flour and water for white face paint, then draw “cracks” on the cheeks with a black marker. Tie hair with ribbons or yarn scraps. If you want to add a creepy touch, sew on mismatched buttons as “eyes” on a headband for a doll-like stare. My twins love this because it’s spooky but still playful.

Amazon picks:

Toddler Girls’ Lace Party Dress




5 Frankenstein and the Bride of Frankenstein




This monster classic is perfect for siblings, and my twins absolutely adore it. They’re too young to understand the whole “Bride” story, but to them, Frankenstein and his Bride are just “Mom and Dad” monsters who belong together. They’ll fight and bicker, but at the end of the day, their twin bond is sacred—there’s no better friend than their sibling. This costume brings out that sweet connection.

Frankenstein DIY:

Start with old black pants and a shirt—rip the knees and fray the edges with your fingers for a tattered look. For the green face, mix green food coloring with flour and water for safe, washable face paint. Draw “stitches” with a black marker across the forehead or cheeks. For neck bolts, paint wine or champagne corks silver (use nail polish or craft paint) and glue them to a headband or pin them to the shirt collar. Stuff the shirt with a pillow for that oversized, clunky Frankenstein vibe—my son loves stomping around like a monster!

Amazon picks:








Bride DIY:

Use an old white dress or a long white T-shirt. For the iconic hair, tease their hair with a comb and spray white streaks with diluted flour-water mix (or use white chalk). Add dramatic eyeliner for a gothic look. If you have an old scarf, drape it over the shoulders for a “veil.” My daughter insists on twirling in her dress, claiming she’s “the prettiest monster ever.”
