Halloween is the perfect holiday to celebrate with friends, and a group costume is an awesome way to commemorate your friendship.

Group Costume DIYs With T-Shirts and Sweatshirts

While Halloween is a holiday we associate with crisp autumn air, in some areas, that isn't always the case. If you live in a region that experiences warmer temperatures late into the year, T-shirts are the perfect base for your group Halloween costume. Here are some top group T-shirt costume ideas.

Colorful Candies

When you think of Halloween, you also think of candy, so it makes sense to dress up as your favorite sweets. Our Hanes 5280 Unisex Essential Short-Sleeve Tee is available in 46 colors, so you and your friends can dress up as every color in a bag of M&Ms or Skittles. Just add the candy logo of your choice to the front of the shirt, and you're good to go.


Everyone has a favorite crayon color, and with the G500 Adult Unisex Heavy Cotton T-Shirt from Gildan, you get 70 colors to choose from. Stunning shades include Cherry Red, Blackberry, and Jade Dome, so you can make sure everybody gets a color they like. A collection of crayons is a great Halloween idea for large groups because there is no limit to how many colors you and your friends can dress up as, and it's pretty easy to add a crayon logo using an iron-on transfer.

Classic Characters

You can also use group Halloween T-shirts to represent your favorite characters from books and movies. For example, if you and your friends want to dress up as "Winnie the Pooh" characters, Piglet can wear a pink T-shirt, Tigger can wear an orange shirt, and so on. Or grab a set of red shirts and some white and black HTV and voila you're Thing 1,2,3 etc! The Bella + Canvas 3001C Unisex Jersey T-Shirt is the perfect canvas for cute character costumes because it's super soft yet holds up well for screen prints and heat transfers.

Super Sweatshirts

If Halloween gets chilly where you live, you can use blank sweatshirts to create your group costume. Here are fun group sweatshirt costumes that will keep you warm and cozy.

Cartoon Characters

Cartoons and animated films are excellent inspirations for group costumes. If your Halloween group is small, you could dress up as Alvin and the Chipmunks. All you need is the Gildan G185 Unisex Heavy Blend Hooded Sweatshirt in red, blue, and green, and you can add the characters' initials to the front of each shirt. If a fourth person wants to join the group, they can dress up as Dave.

The Care Bears and the Seven Dwarfs are great large group costumes using sweatshirts. For the Care Bears group costume, you can add belly badge patches to the Gildan G180 Unisex Heavy Blend 50/50 Fleece Crew Sweatshirt. It's available in 39 colors, so you're sure to find the color that represents your favorite Care Bear. For a Seven Dwarfs group costume, you can add the character names or embellish your sweatshirts with iron-on transfers that look like the dwarf's shirt buttons and belts.

Book Covers

While dressing up as characters from your favorite books is a great group costume idea, you and your friends can also dress up as the books themselves. Popular series like Harry Potter and The Chronicles of Narnia feature enough titles for all your friends to dress up as book covers. With the Jerzees 562 Unisex NuBlend Fleece Crew, you can recreate your favorite book covers with iron-on transfers or fabric paint. You can also decorate one of the sleeves to make it look like the book spine.

Plants and Animals

With some felt and glue, you can transform the Hanes P170 EcoSmart Pullover Hoodie into an animal costume. For example, if you and your friends want to dress up as a shiver of sharks (yes, a group of sharks is called a shiver, lol), you can add felt teeth to the hood's rim and a felt eye to each side.

The EcoSmart hoodie is available in 38 colors, so everyone can dress up as a different animal and celebrate Halloween as a collection of pets or wildlife. You can use the same felt and glue technique to create flowers, and your friends can attend the big Halloween party as a walking, talking garden.

Playing Cards

Get four white sweatshirts and four iron-on transfers, and you and three friends can dress up as the Ace of Spades, Hearts, Diamonds, and Clubs. Larger groups can celebrate Halloween dressed as winning hands like a royal flush or a full house. For a more colorful group costume, you can get red, blue, green, or yellow sweatshirts and decorate them to look like Uno cards.

Another fun card game that's easy to turn into a group costume is Cards Against Humanity. You can use fabric markers to write the fill-in-the-blank questions on black sweatshirts and the answers on white sweatshirts. This costume can work for couples and large groups. Black sweatshirts also make a great canvas for fabric paint you can use to make shirts that look like dominoes or dice.

Trick-or-Treat Bags

The perfect group costume isn't complete without trick-or-treat bags for your group. We offer an incredible selection of blank canvas totes you can use to create bags that match your group Halloween costume. Add spooky graphics, and personalize each bag with a group member's name and "Halloween 2022" to give everyone a holiday keepsake.
