DIY Tulle and Ribbon Skirt

In blue this skirt is perfect for Cinderella, in pink it’s a gorgeous Glenda the Good Witch, and in red you are all set for The Queen of Hearts! Here’s an easy pattern and tutorial for a dreamy children’s costume. I would love to see how you use it in your costume; tag me on Instagram @sewcanshe!
Jack Skellington

Sarah said, “…Costumes can be messy and unfinished. Don’t be afraid to try making a costume. It’s fun!” She’s right; you can use any kind of paint and stitching to make costume magic. Here’s her DIY costume tutorial and pattern links for Jack Skellington.
Rainbows and Sunshine

Is this the cutest children’s costume idea or what? I love this costume for babies and toddlers, but I know you can also adapt it (without changing the size too much) for any size costume. Perhaps twins or besties would rock this look! Head to merrimentdesign to sew the sunshine and rainbow look this year.
Rainbow Unicorn

Rainbows and unicorns – can you even have one without the other? When I was in elementary school I had a purple banana seat bike with a rainbow Pegasus – add some wings to this cute rainbow unicorn pattern and you’re set.
Fabric Butterfly Wings

Did someone say, “Wings”? Indeed, I did! Here is a free pattern for fabric wings in three sizes from Made For Mermaids. Wings are great for costumes and make-believe because they’re so versatile!
Black Panther

My friend, Sarah is so creative! You will appreciate her free sewing pattern for this DIY Black Panther children’s costume. She writes a good pattern, and she shares her learning experiences so that your sewing project will turn out beautifully. I hope you give it a try, or use this as a jumping off point for a different muscled costume.

Totally Girly Clown

I love everything about this colorful girly clown children’s costume from Classy Clutter. I am sure you will be fulfilled as you put the finishing touches of makeup and accessories on your masterpiece!
DIY Costumes for Guardians of the Galaxy

You can check out “Making Halloween – Guardians of the Galaxy” for inspiration and helpful tips. The fun really comes alive when children enter the roll they have chosen. My experience has been that they love what we create (no matter what bits are disappointing to us) and cherish the time we put into their imaginations.
DIY Pirate Costume

Pirates are a classic, and this children’s costume is one of those year-round, always applicable looks. This pattern from Apple Green Cottage is an easy and iconic pirate look.
Nightshade Dress

Wednesday Adams? Yes, please! This free pattern from Mood Fabrics is sure to impress. And I’m sure you will get more than one use out of this beautiful costume!
Easy DIY Crown

Some costumes call for accessories to really finish them properly. Here is a video tutorial for an easy crown for a princess, a king, or a jewelry thief!
Curious George & The Man

Jump over to Sew A Little Seam to see how she made these costumes. Another classic tried-and-true duo for a stellar Halloween haul!
No Sew Baby Pineapple

Pineapples are a hit in Florida right now; they’re everywhere. As a bonus this baby costume is great in Florida because it doesn’t really get cold for Halloween. I steer clear of the full on animal costumes, so this is more like it!
Hoodie Hack Dragon

I love a good shortcut! This one is great because you add the dragon elements onto an existing hoodie; that’s nearly half the work done before you even start. Swoodson Says has the pattern to show you how.
DIY Kids Costume – Easy Gorilla

Make a simple gorilla costume with this DIY Gorilla tutorial. Use lots of existing material, and add the gorilla elements to it!
Fortnite Marshmallow

I kept waiting for Fortnite to go out of style, but it’s got staying power! Sew a Fortnite costume this year for extra fun times!
Felt Masks

Masks can really add a fun touch to a costume. Sew A Little Seam has four patterns for making felt masks that are really well done. And you can make them any color to match your costume; I hate being limited by what the store has to offer.
Mummies!

This is a great tutorial for a mummy costume. It doesn’t take too long, and you will love the results.
Sturdy Wings

This set of wing’s is made using the video tutorial from Seechel’s Vlog. You will be happy with the sturdy construction and versatility of this pattern.
