NUTELLA + BANANA

We can’t think of a better combination than a creamy spread of Nutella over a sweet Banana. Whether it’s in a crepe, sandwich or on top of ice cream (if you haven’t tried it, you need to!) this combo is insanely delicious. And this costume combo? Insanely adorable.

WHERE THE WILD THINGS ARE

Ok, how incredible are these handmade costumes from Boo Bah Blue from the classic storybook, Where The Wild Things Are? Dress your littlest as Max, the boy with the extraordinary imagination, and your oldest as the leader of the “Wild Things” who crowns him king.

RAINBOW + RAINCLOUD 

Bring together sunshine and rain to make an epic rainbow in these weather-themed costumes. Go for the duo from The Costume Cafe or buy individually like this super cute rainbow from Pottery Barn Kids. The forecast for these costumes is clear skies with plenty of smiles ahead!

RINGMASTER + LION

Step right up, step right up, the Halloween circus is coming to town! And who better to lead the charge than your big boy or girl as Ring Master, and little bro or sis as the “mane” attraction, the Lion! This show is sure to be a sellout.

SUSHI ROLLS

It doesn’t get much cuter than this folks. These handmade costumes from The Wishing Elephant will turn your cuties into tiny sushi rolls no one can resist. Featured on The Martha Stewart show, they are high quality with great details like a side of wasabi and pickled ginger! And you don’t need twins to pull this off, the costumes come in sizes from newborn to 24 months, and 3 varieties: salmon, tuna or shrimp!

GARDEN GNOMES

These garden gnome costumes (for girl and boy) are ev-ery-thing. Sit them in your own garden for an unbelievable photo that is sure to be a “framer”. 

ASTRONAUT + ALIEN

If your child is outer space obsessed, turn their astronaut dreams into a paranormal fantasy with the addition of an adorable alien (that just might be lurking on their Halloween mission).

SNOW WHITE + APPLE

Instead of the classic pairing of Snow White and the dwarfs, how about a more unique approach and presenting her with the magical apple instead? This hand crocheted apple hat from Handmade Baby Love is so sweet (and SO easy to slip onto a sleeping newborn), how can Snow White possibly resist a little nibble?

DORY + NEMO

With the recent success of “Finding Dory”, Nemo mania is back in full swing, and what better way to embrace your children’s love of these new Disney classics than dressing them as the dynamic duo. This Dory costume is the prettiest one we’ve seen, while Nemo will stay cuddly and warm on Halloween night.

POKÉMON

With the Pokémon craze still in full force, your kiddos will be thrilled to transform into Ash, the Pokémon trainer, or another favorite character in their Pokédex. Go for the classic Pikachu, fun Charizard or the oh-so-cute Eevee.  

FISHERMAN + FISH

This Fisherman and Fish costume duo is a real catch. And side-by-side they’ll be reeling in the Halloween candy hook, line and sinker!

TORTOISE + HARE

The beloved story of the slow and steady Tortoise, beating the too-confident Hare is a mainstay in children’s literature, so everyone will connect with this costume pairing depicting the 2 main characters. But we’ll be telling our kids “slow and steady wins the race” while they are upwrapping their Halloween candy, whether they wear these costumes or not!

GHOSTBUSTER + GHOST

Coming off a remake of the popular ’80s movie that people love to watch over and over again, this sibling costume is perfect for those kids’ who want a cool accessory “weapon” (as the Ghostbuster) and a little one (or mom!) who just wants to keep it simple (as the Ghost). Who ya gonna call? Ghostbusters!

WINNIE THE POOH + TIGGER + PIGLET

Turn up the “aww” factor by dressing your brood as these treasured storybook characters. These Winnie The Pooh, Tigger, and Piglet costumes are all plush and soft, so your kids will stay comfy and warm throughout their Trick or Treating adventures.

ELEPHANT + PEANUT

This fun combination is sure to get a chuckle from your neighbors as you make the rounds Halloween night. A cuddly elephant for your toddler or big kid, and a little peanut for, well, your little peanut.

LITTLE RED HIDING HOOD + WOLF + GRANDMA

“My Grandma, what big teeth you have!” Reenact this classic fairytale with these incredible costumes inspired by Little Red Riding Hood. The girls’ version of the wolf costume is so fun (those boot covers!) and still girlie while providing ample coverage (you know what we’re talking about, right mom?!), and the boys’ version from Boo Bah Blue is so darling and comfy. And if you’ve got a 3rd kid to throw into the mix, may we suggest this incredible handmade yarn wig from Yum Baby for an amazing Grandma!

PETER PAN + HOOK + TINKERBELL

CHEF + LOBSTER

What’s better than lobster? A baby dressed up as a lobster of course. And paired with a hungry chef, well, let’s just say things could get dicey.

STAR WARS – LUKE + REY + YODA

This is a sibling costume trio from a Star Wars galaxy far, far away. Go with Luke for your light-saber loving guy, Rey for your strong and independent gal, and who can resist this hand knitted hat and cocoon for a teeny tiny Yoda. Halloween we love.

CATERPILLAR + BUTTERFLY

Turn one of nature’s most incredible transformations into an incredible Halloween pair. It’s a winning combo for everyone: little caterpillar gets to stay cozy and warm, while Ms. Butterfly gets the pretty tulle and wings she’s always dreamed of.

WIZARD OF OZ

We must admit, this is one of our favorite group costume ideas of all time. Each character from the Wizard of Oz can come to life in its own unique way – with Dorothy, the Scarecrow and the Tinman all so different, yet when together they form a wonderful homage to the classic movie. Follow the yellow brick road and perhaps it will lead to candy land!

PEANUT BUTTER + JELLY

Every child’s favorite sandwich combo is larger than life with this fun Peanut Butter & Jelly sandwich costume set – perfect for throwing on over their regular clothes for an easy costume (especially for older kids who may be “over” all the bells and whistles and are just out for the candy!)

PEANUTS PALS

Take your pick from these lovable characters from the Peanuts comic strip: the oh-shucks leader Charlie Brown, cuddly puppy Snoopy, best bud Lucy, or even fuzzy Woodstock. Your Peanuts clan is sure to get plenty of “good grief!”s (in a good way!) on Halloween night.

LITTLE BO PEEP + HER SHEEP

Little Bo Peep has lost her sheep, but luckily you know right where to find him (or at least we hope!). Your little girl will love all the frills and fluff of this classic nursery rhyme costume, and that sheep has got to be one of the cutest costumes we’ve seen for a baby or toddler. 

BREAKFAST FAVORITES

The Costume Cafe is one of our favorite places to go for unique (and adorable) handmade costumes, and this combination of Breakfast Favorites does not disappoint. You can pick different sizes for each costume (from newborn to adult), and we just love the added touch of the Butter Hat with the Stack of Pancakes, and the bacon hat with the Sunny Side Up Egg.

BURGER + FRIES

Another genius costume from The Costume Cafe are these super sweet Hamburger and French Fries – complete with pickle hat and squirt of ketchup! They are soft and easy to fit over regular clothes – just make sure to put in your order early!

DINER WAITRESS + WAITER

Order’s up! These unique retro costumes for a diner waitress and waiter are simple and fun, and can be amped up with some play kitchen food that’s sure to be hanging around your house. And how amazing would they be paired with the burger and fries or Breakfast Favorites costumes above?!

HOT DOG + KETCHUP

Another classic food combination comes to life with a hot dog toddler and his sidekick condiment: ketchup. And this ketchup costume is perfect for a little one who isn’t yet on-the-move…they’ll stay warm and snug in their packet, all night long. Squeezes required!

COP + ROBBER + CONVICT

This is a super fun costume trio (that can easily be a duo too) that combines a pesky robber with a no-nonsense cop, and a convicted felon! Hopefully the streets will be safe on Halloween night with this crew running around!

TROLLS

Hair up! If your kids were big fans of the Trolls movie like ours, then they’ll love these fun dress-up versions of Poppy and Branch. Snatch them up before the Bergens do!

JAKE + NEVERLAND PIRATE

Got a Jake and the Neverland Pirates devotee? This handmade Jake costume from Heavenly Things For You is the sweetest we’ve seen, and exceptionally well-made. Add in a cute lil’ pirate, and you’ve got a swashbuckling pair ready to pillage for some loot!
