Boo! 3 Last Minute Halloween Costumes for Babies that Are Actually Super Cute

Halloween is just a handful of days away and I couldn’t let it pass me by without a few last minute Halloween costume ideas. Especially since it’s Hayes’ first Halloween.

I put together three last minute Halloween costumes specifically for babies and toddlers, in partnership with Uber. And they are so cute I can hardly handle it. Don’t have a baby? No worries. These costumes can easily be tweaked for older kids AND adults.

Click through for all 3 DIY Halloween costume ideas!

First up, is a DIY clown costume! And while I’m firmly in the ‘adult clowns creep me out’ camp, baby clowns are pretty cute in my book. We dressed up Hayes in this option for a little neighborhood Halloween thing we went to and used the Pickup Messages feature to message our Uber drive-partner on the way back home that I’d be the one holding the baby clown. Never thought that sentence would come out of my mouth before now. Haha. But we all got a kick out of it, and in a sea of other costumed-up kiddos, it was helpful identifier.

Since we’re a one car family, I rely on Uber pretty frequently to get me where I need to go when Jeff has the car – meeting up with friends, picking up lunch, etc. Or most recently…to get to the neighborhood Halloween party without the headache of trying to find parking. AND to run errands, like gathering up the craft supplies for these costumes. And speaking of supplies…

Here’s how to make a DIY clown costume, a cute little mouse costume, and last but not least a moon costume.

DIY Costume for Babies #1: Clown

My mom made me a clown costume for my very first Halloween. And I wanted Hayes to have one too, so here we are…

To make your own DIY clown costume, you’ll need a funky outfit, a pom pom maker, yarn, scrap fabric, scissors, and a sewing machine.

Start by making 3 small to medium size pom poms with a pom pom maker. Attach two of the pom poms to the pants or overall section of the outfit, with a needle and thread (or sewing machine).

Then, for the fabric collar, you can tweak the dimensions based on the size of your baby or toddler. But for Hayes since he’s not even a month old yet, the collar was pretty small. The dimensions for mine were an 8 inch circumference circle for the top layer with a four inch cut out circle in the middle for the neck and a 9 inch circle with a four inch cut out circle for the second / bottom layer. Then, cut a slit, sew around the neck to create a 1/4 inch inseam that you will then feed a string through using a safety pin to fish it through. The string will allow you to gather the fabric and create a ruffle when tied. Then sew the two pieces together (you must tack them together on the sides).

Next, for the hat, use a thick fabric that is sturdy enough to stand on it’s own OR use a heavyweight canvas and a thinner fabric on top. Cut out 2 triangles that are 5 inches long on every side. Then sew up two of the three sides either by hand or on a sewing machine. Now attach two strings (or two thin strips of the same fabric) to the bottom / open area of the hat. Attach one of the three pom poms to the top of the hat. All done!

DIY Costume for Babies #2: Mouse

This mouse costume is the easiest option of the three to recreate and could be tweaked to pretty much any animal you can think of, if you change the colors. I thought a mouse costume was a cute option for a baby though.

To make your own, you’ll need a white onesie and a white hat (with or without animal ears), pink scrap fabric, heat bond fabric tape, an iron, and a small piece of pink yarn.

And to make this costume, cut out an oval shape in a light pink fabric and adhere with a no-sew heat bond tape and an iron according to instructions. Then either create two mouse ears with fabric and attach to a baby hat / bonnet OR find one that already has ears like mine and attach small pink ear pieces to the inside of the existing ears. Lastly, add a 6-8 inch piece of pink yarn to the back of the onesie for the mouse tail. And that’s it!

DIY Costume for Babies #3: Moon and Stars

Since Hayes’ middle name is moon, I HAD to make him a moon costume! For this one, you’ll need a onesie, yellow fabric, polyfill (pillow stuffing), scissors, a sewing machine, and a needle and thread.

You’ll make the moon and star in pretty much the same ways. And each piece will eventually be attached to a solid color onesie. Start by drawing out a crescent moon shape and a star shape. Double up the fabric and cut about 1/4 inch outside of each tracing – so you’ll be left with two identical shapes (two fabric pieces for the moon and two fabric pieces for the star) that are each slightly larger than what the finished shapes will end up being.

Pin the moon pieces together and separately pin the star pieces together. Sew along each shape but leave about a one inch opening for the polyester fiberfill to go into. Be sure to back stitch on either side of the opening. Flip the shapes inside out and fill with pillow polyester fiberfill. Then hand sew the remaining opening for each shape with a needle and thread (an invisible stitch works best).

And then, attach the moon and the star to a onesie with a needle and thread. When Halloween is over, you can remove the moon and star shapes from the onesie with a seam ripper without damaging it, so you can reuse the onesie. Keep the star and moon too as decorative keepsakes for your kid’s room.
