  • Building the Wall
    • Reinforce the corners of a cardboard box with some extra cardboard so it keeps its shape.
    • Make the Wall: Paint the boxes like brick walls and cut out all but the four sides.
    • Attach a string to the front and back of the boxes and we used that to drape them over our shoulders.
  • Make the Body
    • Sew two 15-inch tubes from old fabric about long to use as legs
    • Stuff with hand towels
    • Pin to the inside of a pair of baby shoes or socks
    • Attach the legs to the inside of the boxes so that they looked as they were hanging over the wall.

Santa Claus: "His belly shook when he laughed like a bowl full of jelly." Don a Santa costume. No need to pad the belly this year! Perhaps your partner would agree to be Mrs. Claus. Kids could dress as elves.

Construction Worker Outfit: Wear a tool belt filled with bottles, diapers, wipes, medicine droppers, and don't forget the hard hat!

Black Widow: Wear all black and paint a red circle on your shirt. Make some legs and hang them with string from your arms.

Mommy and Me Costumes

This category is perfect for those wishing to showcase your growing little one/s for their truly "first" Halloween! We can assure you that it will be a treat for everyone at the party!

Mommy and Baby Skeletons: A skeleton with a baby skeleton on the bump is great way to feature the bump in the first or second trimester. It's also a fun way to let people know you're pregnant! Here's how to reveal your wee one:

  • Start with an over-sized black shirt, black pants and black gloves
  • Cut the bones for mom and baby from white craft foam
  • Sew or glue in place
  • Alternatively, paint with white craft paint

Cat and Fish: Paint your belly blue and add some colorful fish. Your hubby can dress as a hungry cat.

Peek-a-boo-baby: With a painted baby face on your belly, wear a button-down shirt to make it look like the baby is peeking out.

Special Bump Costumes

How about making that bump THE costume? Imagine all the great things you can do with that ball-shaped belly! Depending on weather, paint it (or your shirt) as a pumpkin, a world globe, a sunflower or a ball and create a costume accenting the bump. You don't have to expose your whole torso; just cut a hole in your shirt and let the painted bulge poke through.

Pumpkin: Costumes can range from a simple orange t-shirt with a painted face to a elaborately painted belly. Here's how one mpumpkin shirt with baby bulgeom-to-be became a pumpkin in the patch:

  • Make the patch: Cut leaves from green felt (two 8x11 pieces should be enough). Hot glue or sew to a dark colored sports bra. Add dangling artificial ivy, allowing the ends to dangle freely.
  • Add the pumpkin: Using craft paint, create a pumpkin from your bump. Better yet, have your partner or a friend do the art work!

Crystal ball: Your painted white belly can stick out of your gypsy costume while you read people's futures.

Beach bum: Proud of your pregnant figure? Put on a bikini and paint your belly like a beach ball. Pretend you're carrying it around.

Mother Earth: Dress in a flowing green gown, wrap yourself in some vines and put flowers in your hair. To really drive home the point, paint the earth on your belly and let it show.

Lady Bug: Paint the bump bright red and add black spots.

Flower child: Braid your hair, wear some 60's clothes, and paint a peace sign or smiley face on your belly. Free love, man.

Gardener Pumpkin, beans, peanuts are popular names for little ones in womb. Add those and gardening tools to your costume.

Safety Precautions

Homemade costumes can be flammable. Be safe with this precautions:

  • Stay away from naked flames
  • Use naturally flame-proof materials where possible
  • Have a fire retardant base layer
  • Design your costume for quick escape. Cut the sides and then velcro up the costume so it can be easily ripped off in the event of a fire.

Practical Tips

  • Think cool: Keep in mind how long you will be wearing your costume.
  • Easy in and out: More frequent bathroom trips are the "new norm" for mommy-to-be (often with a 30 second warning window!) Pick a costume that doesn't make those trips more difficult!
  • Comfort: Beware of choosing something restrictive and confining. Being miserable even while looking great, is't worth it!

Have fun! Whatever you choose, remember to enjoy yourself and your baby. You're already a "treat" for all those around you!
