Creepy Carnival

Step right up to a creepy carnival extravaganza! Think vintage circus vibes, with contortionists, fortune tellers, and cotton candy.

Design a t-shirt featuring a menacing clown face or a mysterious fortune teller's tent. Combine with carnival games and food like corn dogs, caramel apples, popcorn and cotton candy.

Enchanted Forest

Transport your guests to an enchanted forest filled with mystical creatures and magical surprises. Think whimsical owls, mischievous fairies, or towering old trees. A few fairy lights and dim lighting can give your event a magical feel indoors or out.

Perfect for nature lovers, the enchanted forest theme can see costumes along the lines of mushrooms, pixies, butterflies, elves, fairies, gnomes and all sorts of playful creatures!

Haunted House

Turn your home into a haunted mansion with eerie decorations and spine-chilling surprises around every corner. A spooky mansion silhouette or ghostly apparitions could be the costume of the year with a haunted house theme. You can really push the boat out and give your guests a jump scare or two throughout the night.

A haunted house party theme can keep your guest’s hearts racing.

Pumpkin Patch Party

Celebrate the harvest season with a pumpkin patch-themed gathering. Design costumes and party accessories featuring adorable pumpkins, scarecrows, and fall leaves for a cozy touch. This is perfect for a kids event (imagine a room of toddlers all sitting in matching pumpkin outfits!) but is perfect for a warming fall party or event too.

Mystical Masquerade

Host an elegant masquerade ball with an air of mystery and magic. A masquerade ball is a popular event, with swirling masks, big hair and fancy attire. Can’t quite splash on a full ball? No problem! Our shirt templates can feature different styles of masks and a Mardi Gras feel.

Witch's Coven

Nothing says spooky more than a witch’s coven. Gather your friends for a night of spellbinding enchantment. Feature cauldrons, broomsticks, or whimsical potion bottles to match your witchy attire. A witch’s coven should be full of black, smoky purples and deep, dusky greens for a truly Halloween feel.

Alien Abduction

Take a cosmic twist on Halloween by throwing an alien-themed party. Design t-shirts with quirky extraterrestrial figures and flying saucers for a spacey touch. The best part about this theme is that your aliens can look like anything you can think of! Different colors, extra limbs or even a few extra eyes for luck, an alien theme is always a big hit with friends, family, colleagues and clients!

Monster Mash-Up

Combine various classic monsters like vampires, werewolves, and mummies into one quirky and fun party. T-shirt designs could feature a playful mishmash of these creatures or could allow you to show off your favorite. You don’t need to stick with a traditional monster though - unleash your creativity and design your own monster to scare the guests with.

Dia de los Muertos Celebration

Honor the Mexican tradition of Day of the Dead with vibrant colors, sugar skulls, and marigold decorations. T-shirt designs could incorporate ornate sugar skull designs or marigold motifs.

Underworld Mythology

Delve into ancient myths and legends with a theme centered around gods, goddesses, and mythical creatures. T-shirt designs might feature symbols of different mythologies. From Greek and Norse, to Roman and Japanese, as well as plenty of other sources to pull from, the possibilities are endless with this theme.

Mad Scientist Lab

Embrace your inner scientist by transforming your party space into a crazy laboratory. Incorporate bubbling potions, beakers, and quirky science equipment into your theme. In fact, this is a great theme for a cocktail party where guests get to experiment with their very own flavors and drinks. Add a curly wig for an even better costume.

Spooky Safari

Go on a mystical safari where guests encounter fantastical creatures like unicorns, griffins, and dragons. T-shirt designs could showcase these mythical beasts in a creative way to get everyone really into the theme. This kind of safari can be complemented greatly by figurines to really set the scene as one of the scariest Halloween party theme ideas.

Ghoulish Garden

Turn your backyard into a spooky garden filled with larger-than-life insects, carnivorous plants, and eerie garden gnomes. Design t-shirts featuring these garden-dwelling terrors and ‘green up’ your space. This is a great idea for an eco-friendly business or event to keep plants or garden equipment/furniture at the forefront and is one of the most popular out of our halloween party themes.

Time-Traveling Costume Party

Explore various eras of history with a time-traveling costume party - one of our most out-there Halloween party theme ideas. T-shirt designs could represent different historical periods, from the Victorian era to the roaring twenties. You can niche this into one specific century or era or you can let everyone bring their own unique designs from any era they want! It doesn’t have to be super historical either - you could even opt for a 70’s, 80’s or 90’s party!

Ghostly Gala

Host a classy black-and-white ghost-themed soirée with a vintage touch. T-shirt designs might include elegant Victorian-style ghosts or intricate cobweb patterns.
