1) Kitty Costume with Gold Leopard PJ Print

Transform your little one into a cute and cuddly kitty with just a Gold Leopard Print Stretch Pajama Set and some creative eyeliner skills.

For the ears, simply cut triangles from felt and hot glue them onto a headband. This costume is the purr-fect solution for a quick and adorable Halloween costume.

2) Space Themed Galaxy Costume with Mightly Organic Cotton Galaxy Print PJs

Transform your kid into a queen or king of the galaxy with just a pair of Mightly Organic Cotton  Galaxy Print PJs. Using construction paper, aluminum foil, cardboard, pom-poms, yarn, and a hot glue gun, Modge Podge or glue, create a “solar system” necklace. Hang the planets from a string of yarn with pom-poms and pieces of aluminum foil to make shiny asteroids. To complete the look, sprinkle some glitter on their face and sport some glow-in-the-dark wristbands or necklaces. Your little astronaut will be amazed by the night sky.

3) Superhero Costume with Capes

Make your child's dreams come true by turning them into a superhero with personalized capes. Cut out a large “S” for Super-girl or -man or “B” for Bat-girl or -man from felt and pin it onto the back of a plain colored tee, like the Mightly Long Sleeve Pocket Tee (pinning will ensure you don't ruin your favorite tee). Cut out a matching cape from a sheet or use a solid-colored sheet to make a cape. You can also add some extra embellishments like a utility belt to really finish the look. Get creative and come up with your little one’s own superhero identity and let them run wild on Halloween night.

4) French Fille or Fils (aka, girl or boy) Costume with Striped PJ Shirt and Bandana

Bonjour! Turn your kid into a posh Parisien with just a few pieces of clothing. A striped Mightly PJ shirt with some black sweat pants or leggings with a red scarf tied around the neck. Top it all off with a beret for extra class and style. You can even turn a piece of cardboard into an artist's paint palette and accessorize to your heart's content. This costume will make them feel like they're on the way to the Eiffel Tower!



5) Chef Costume with Apron and Chef's Hat

If your kid loves being in the kitchen, then this costume will be a perfect fit for them. Simply grab an apron, chef’s hat, and their favorite recipe book. You can also give them a whisk or spatula as a prop. Let them carry around a mixing bowl or baking tray and mismatched socks to complete the whole look. Your little chef will see Halloween as an opportunity to have fun in the kitchen.
