Old Lady

Cute and Adorable DIY Baby Halloween costumes for your little one. Dress them up with family or by themselves and use a carrier, wagon, or stroller too!

If you’re making an old lady costume for your baby, you definitely need a floral dress cardigan set, for starters. I love the way crocheted knee high socks look on chubby little baby legs too! To make the wig, I used 1-inch white poms (cotton balls would also work) and glued them to a tight knit cap. For the knit cap, I actually used her newborn hat from the hospital.

Ghost

Take a look at these photos and basic instructions for this no-sew ghost costume using white fleece, black felt, and fabric glue, and then create something truly unique with your own flair.

Chick Fil A Cow

How adorable is this little baby cow (or calf)?! Grab a simple baby cow costume and make your own Eat More Chikin sign and you have an easy baby Halloween costume.

Cuties

This is a great costume for a baby who’s not yet on the move. Have an extra box of orange cuties? Stick your little one in there with an orange onesie, orange cap, and blow up some orange balloons.

Little Lamb

Using cottons balls, some black felt, and all over black pajamas, you can make a DIY baby lamb costume. View the whole tutorial on Make-It-Love-It.

The Little Mermaid

For a DIY mermaid costume for your baby, make a wig by crocheting a beanie onto a yarn piece. For the top, sew elastic sequin fabric into three separate pieces, two for the arms and one bigger piece for bodice and connect them at the underarm. For the tail, use about a 1/2 yard of netted blue sequin fabric with some stretch in it. Check out full tutorial here.

Mouse in a Mousetrap

It’s a great idea to incorporate a transporting device for your baby’s Halloween costume since they’ll be wheeled around the whole time they’re trick-or-treating. This Mousetrap was made out of Birch wood, sponge for the cheese, and painted PVC pipe with irrigation tubing for the coil. All of this was rested on a wagon with a mouse costume to top it off.

Olaf

Of course you can buy an Olaf costume for your baby which would go great with an older sister Elsa! For a DIY Olaf costume, use some white and orange fleece, black felt, and a brown under shirt. View full tutorial here.

Cactus

This is a simple DIY baby costume. Using a full green fleece onesie, attach some pieces of white yarn for the cactus spikes. Add some felt flowers to complete the costume.

Garden Gnome

For this DIY Gnome costume, gather simple materials like an over-sized sweater, a pair of bulky pants high boots, red and white felt, big buttons, and an old belt.

Jack Jack from the Incredibles

Such a simple costume idea for the Incredibles. Simply put your baby in a red footed pajama outfit and a cheap, black eye mask. You can also add the Incredible logo on the front of his shirt with either a sticker, iron on label, or make it yourself with felt.
