Thanks to TikTok and Instagram, coquette style — a blend of vintage and romantic flair — has surged in popularity. This kid’s party took the feminine aesthetic and paired it with the birthday girl’s favorite movie: Harry Potter. The outcome? An incredibly unique and reimagined version of a classic kids party theme, featuring owl-topped Lambeth cakes, pink bow-wearing toads, and blushing London telephone booths.
“A trip around the sun” is a birthday party theme as cheery as it sounds. Each detail of this party shined bright, from the yellow palette to a sun-shaped balloon entrance, woven rays backdrop, and saturated, picnic-inspired tables. We love how this special celebration added bohemian elements to the design, from rope vases to wood chargers — but the theme itself can truly pair with any family’s distinct style.
It’s no surprise mini Swifties are opting for Taylor Swift-themed parties, and this 5th birthday left no blank space. Each corner of the party was dedicated to one of Taylor’s 11 albums — from a purple Speak Now piano corner to a Midnights ball pit, Fearless guitar stage, and a Lover dessert bar. Creativity is Taylor’s specialty — and an absolute must when it comes to a Taylor Swift-themed party.
A whole new world — in your backyard. This birthday party transformed a lucky 8-year-old’s home into a video game-inspired world made up of Minecraft-influenced blocks and décor. Replicating the game’s different features, the party boasted a “survival mode” photo op, “adventure mode” bounce house, and “creative mode” crafts. Parents stayed in “spectator mode,” of course, enjoying freshly catered pasta salad, fruit bowls, and more.
Wild West moments are going coast-to-coast in 2025 — and this 4th birthday party proves why. Succulent centerpieces, desert-inspired place settings, and a mirage of suspended cowgirl hats impressed even the adult guests in attendance. While kids enjoyed cactus cupcakes and cotton candy animals, parents sipped on monogrammed lattes and cowboy boot-adorned cocktails. It’s safe to say this kids’ party theme is anything but dry for all ages.
This kid’s party theme is our jam. The “berry first” birthday left a sweet impression from its strawberry colander towers, berry-colored floral baskets, and fruit-frosted cakes. Parents had their choice of fresh berry-infused cocktails, including spiked strawberry lemonades and strawberry mojitos (yes, please), while their little ones played blissfully with berry blocks and a berry-hued ball pit. We can’t get enough of this fruitful kids party inspiration.
Add lobster bake to the list of clever kids’ party themes you’ve never seen before — but would love to take a crack at. This summer birthday brought a backyard beach club lobster bake to life with custom lounge chairs, towels, pool floats, and more. As for the tables, playful lobster “claws” accentuated centerpieces alongside fishernet runners and nautical rope vases. The parents’ menu included lobster, of course, along with fresh oysters and coconut cocktails.
Fancy Nancy is all about a girl who has extravagant taste, a sophisticated vocabulary, and a love for lavish tea parties. Needless to say, a Fancy Nancy-themed birthday party is feminine, fabulous, and floral-filled. This themed birthday was just that, featuring an accessory wall for young guests to dress to the nines (think hot pink feather boas, butterfly wings, tiaras, and plastic kitten heels). Kid-friendly china, intricate linen, and pastel floral centerpieces created a stunning tea party for the birthday girl and her friends to sip and savor.
This is Halloween — for October birthdays. Tim Burton’s The Nightmare Before Christmas inspired this 2nd birthday party, with a black and white palette and details that would make Jack Skellington proud. Spooky style never looked so good, with black marble tables, smokey ghost chairs, matte black balloons, and perfectly drawn up backdrops. We are particularly infatuated with the ghost-shaped cotton candy station and main character pop tarts.
Bring your little one’s favorite fictional town to life with a Ponyville-themed birthday party. This magical celebration looked straight out of a cheerful coloring book — from the saturated backdrops all the way down to the pastel burger buns. Little ones meandered from a “sugarcube corner” filled with cake to a rainbow bounce house, paint-your-own-trophy table, air brush truck, “pretty pony” parlor, and more. We give this celebration first place for creativity.
