10+ Adorable Girl Toddler Halloween Costume Ideas You Have To See

Halloween with little ones is equal parts chaos and cuteness overload. Between the sugar highs, the costume battles, and trying to get at least one non-blurry photo before someone cries—it’s a whole thing.

But when the costume does come together? Magic. Whether you’re going for laughs, nostalgia, or just something that doesn’t itch, these toddler and family costumes totally nailed it.

And hey, if you’re still figuring out what your kid’s gonna be five minutes before trick-or-treating… been there.

Girl Toddler Halloween Costume Ideas

Cutest Little Mechanic

Okay, but how powerful does this tiny Rosie look? Like she’s ready to take over the whole job site and still be home in time for a nap.

The rolled sleeves, the little work boots, the name patch—it’s all just too good. And that red polka dot headband? Icon behavior.

The Cutest Snow White in the Whole Orchard

Okay but like, can we talk about this tiny Snow White? Because I’m obsessed.

That red bow? Iconic. The little puffy sleeves? Literal perfection. And the basket of apples?? I mean, it’s almost too on the nose—like if she actually bites one, I might start yelling for the dwarfs.

Last year, I tried to get my daughter to dress as Snow White and she absolutely refused because she said the “sleeves looked itchy.” This little one, though? She’s clearly living her fairytale best life.

Honestly, I wouldn’t be surprised if a few squirrels showed up to help her carry that basket.

Cruella and Her (Very Willing) Dalmatians

This family crushed it!

Cruella looks like she walked straight off a movie set, the dad is giving serious “I did this for love” energy, and those little spotted pups? Pure Halloween gold.

Plus the baby dalmatian just casually napping in Mom’s arms? I can’t.

A Boo-tiful Little Ghost

Okay, this is probably the least spooky ghost I’ve ever seen and honestly, I’m not even mad about it.

That fluffy tulle? The sweet little bow? She’s more likely to hand out hugs than haunt a hallway. If this ghost showed up in my house, I’d be like, “Here, take my candy, you adorable menace.”

There’s No Crying in Trick-or-Treating

Okay, I literally can’t handle this. A toddler dressed as one of the Rockford Peaches? My heart.

The pink dress, the little red cap, the war paint under her eyes—it’s giving serious “game face,” even if her bat is probably made of foam.

She looks like she’s waiting for her turn at bat… or maybe just for someone to hand her a juice box.

Straight Outta Paris (and My Bookshelf)

Oh my heart, it’s Madeline! The yellow hat, the little blue dress with that red bow, even the book in her lap—this kid understood the assignment and then some.

She looks like she just marched out of the pages of the book and is ready to politely correct your French.

Yabba Dabba Cute

Okay but someone tell Bedrock there’s a new star in town. This teeny Pebbles costume is too much—I’m actually squealing.

The bright orange dress, the bone details, the hair bow that’s somehow bigger than her entire foot? 10/10. She looks like she could bop Bamm-Bamm with a stuffed club and then ask sweetly for a snack.

Cindy Lou Who (and She Couldn’t Be More Than Two)

I mean… come on.

The tiny pink nightgown? The big red bows? That innocent little smile that probably melts even the Grinch’s cold green heart?

This Cindy Lou costume is everything. She’s got that “Who-ville wonder” vibe down to a science.

Baby’s First PSL (Pumpkin Spice Little)

Okay wait, this is too good. A baby dressed as a Starbucks cup??

I’m losing it. The whipped cream ruffles, the iconic green straw hat, the little leggings—it’s giving “extra foam and extra cute.”

If this baby walked into a coffee shop, I’d 100% try to order her.

Monsters, Inc. But Make It a Family Affair

Tell me this isn’t the cutest little monster squad you’ve ever seen!

Mom as Mike Wazowski, Dad as a fuzzy blue Sulley, and that tiny Boo in her sparkly purple disguise? I’m OBSESSED!
