Halloween costumes do not have to be expensive, complicated, or made completely from scratch. Some of the cutest DIY Halloween costumes for girls can start with clothes already hiding in a closet: an oversized sweatshirt, an old tulle skirt, a party dress, a hoodie, or a pair of denim overalls.
These easy upcycled Halloween costume ideas for girls are perfect for parents who want something creative without spending hours sewing. Most of the projects use felt, fabric scraps, ribbon, and a few simple sewing techniques, making them beginner-friendly and easy to customize.
Below are five adorable DIY costumes you can make from clothes she already owns, including a strawberry sweatshirt, moon-and-stars fairy, Glinda-inspired good witch, spider hoodie, and Jessie-inspired cowgirl costume.
1. DIY Cute Strawberry Costume From an Oversized Sweatshirt

A red or pink oversized sweatshirt makes the perfect starting point for an adorable strawberry Halloween costume. This project is especially easy because the sweatshirt becomes the entire costume base.
Materials
- Red, coral, or pink oversized sweatshirt
- White or cream felt
- Green felt or fleece
- Matching thread
- Fabric scissors
- Pins or sewing clips
- Sewing machine or hand-sewing needle
- Optional green headband
- Black leggings or tights
Step 1: Prepare the Sweatshirt
Wash and dry the sweatshirt before beginning. Lay it flat and lightly press out any wrinkles.
An oversized sweatshirt works especially well because it creates a cute tunic-style silhouette when worn over leggings.
Step 2: Cut the Strawberry Seeds
Cut approximately 20–30 small teardrop shapes from white or cream felt.
Make the seeds about 1 to 1½ inches long. They do not have to be perfectly identical.
Step 3: Arrange the Seeds
Scatter the felt seeds across the front, sleeves, and back of the sweatshirt.
Keep the spacing slightly irregular so the sweatshirt looks more like a real strawberry.
Pin or clip everything in place.
Step 4: Sew the Seeds
Use a straight stitch or small zigzag stitch around each seed.
For an even faster version, use washable fabric glue instead of sewing.
Step 5: Add Strawberry Leaves
Cut 5–7 large pointed leaf shapes from green felt.
Arrange them around the neckline so they look like the leafy top of a strawberry. Stitch along the upper edges.
You can also glue smaller felt leaves to a headband for an easy matching accessory.
Pair the finished sweatshirt with leggings, sneakers, and a green bow.
2. Turn an Old Tulle Skirt Into a Moon & Stars Fairy Costume

That old tutu or tulle skirt she no longer wears can easily become a magical moon-and-stars fairy Halloween costume.
Materials
- Old navy, black, gray, lavender, or blue tulle skirt
- Plain long-sleeve shirt or leotard
- Silver, gold, white, or glitter felt
- Ribbon scraps
- Fabric scissors
- Needle and thread
- Optional glitter tulle
- Headband
- Cardboard or wire for wings
Step 1: Refresh the Tulle Skirt
Shake out the skirt and trim any damaged or uneven tulle.
If the skirt looks too short, tie extra strips of tulle or ribbon around the waistband to add fullness and movement.
Step 2: Cut Moon and Star Shapes
Cut several stars in different sizes from metallic or glitter felt.
Cut one or two crescent moon shapes as larger focal decorations.
Step 3: Decorate the Skirt
Scatter the stars around the tulle.
Hand sew each shape to one or two layers of tulle using a few small stitches. Avoid sewing through every layer because the skirt should remain soft and flowing.
Step 4: Make the Fairy Top
Pair the skirt with a black, navy, or lavender shirt.
Add a few smaller felt stars around one shoulder or neckline.
Step 5: Create Simple Fairy Wings
Cut two wing shapes from lightweight cardboard and cover them with leftover tulle.
Attach ribbon shoulder straps to the back.
Finish the costume with a moon-and-star headband and sparkly shoes.
3. Upcycled Glinda-Inspired Good Witch Costume From a Dress

A pink party dress, flower-girl dress, or old princess dress can become an enchanting Glinda-inspired good witch costume with just a few additions.
Materials
- Pink or blush dress
- Pink tulle
- Silver or iridescent fabric scraps
- Rhinestones or sequins
- Ribbon
- Felt
- Headband
- Cardstock
- Hot glue or fabric glue
- Needle and thread
Step 1: Choose the Dress
Start with any pink dress that still fits comfortably.
Even a simple knit dress works because the accessories create most of the magical effect.
Step 2: Add Sparkly Stars
Cut small stars from silver, iridescent, or glitter felt.
Place them along the bodice and skirt.
Hand stitch the stars in place or attach them with fabric glue.
Step 3: Add More Volume
Tie strips of pink tulle around the waist or attach a removable tulle overskirt to an elastic waistband.
This instantly makes a basic dress feel much more dramatic.
Step 4: Make the Crown
Cut a crown shape from glitter cardstock or stiff felt.
Decorate it with stars, rhinestones, and sequins.
Attach it to a headband with hot glue.
Step 5: Make a Wand
Cut a large star from sturdy cardboard and cover it with silver fabric or glitter paper.
Glue it to a wooden dowel or paper straw and tie ribbons beneath the star.
Add ballet flats and a sparkly cardigan if Halloween night is chilly.
4. Cute Spider Costume From a Hoodie

A black hoodie can become an incredibly cute spider costume with a handful of fabric scraps.
Materials
- Black hoodie
- Black leggings or sweatpants
- Old black T-shirt, tights, or jersey scraps
- Polyester fiberfill
- Black ribbon or elastic
- White felt
- Black felt
- Sewing machine
- Thread
- Safety pins or sewing clips
Step 1: Make the Extra Spider Legs
Cut six long rectangles from black fabric.
Fold each rectangle lengthwise with right sides together.
Sew along the long edge and one short end.
Turn right side out and lightly stuff with fiberfill.
Step 2: Attach the Legs
Sew three stuffed legs along each side of the hoodie.
Position them between the underarm and waist.
Step 3: Connect the Legs
Cut short pieces of black ribbon.
Attach one end to the sleeve and the other ends to the extra spider legs.
When she raises her arms, all of the spider legs will lift together.
Step 4: Make Spider Eyes
Cut circles from white and black felt.
Layer them into large cartoon eyes and sew them onto the hood.
Use four or even six eyes for an extra-fun spider look.
Step 5: Finish the Costume
Pair the hoodie with black leggings and sneakers.
For a softer, less spooky version, add a purple or pink bow near one spider eye.
5. DIY Jessie-Inspired Cowgirl Costume From Old Denim Overalls

Old denim overalls are practically begging to become a fun cowgirl Halloween costume.
Materials
- Denim overalls
- White long-sleeve shirt
- Yellow felt
- Red ribbon or ric-rac
- Cow-print fabric scraps
- Brown or red hat
- Red bandana
- Fabric scissors
- Thread
- Sewing machine
Step 1: Start With the Clothes
Pair old denim overalls with a plain white shirt.
The costume already has its basic cowgirl shape before you sew anything.
Step 2: Add Yellow Cuffs
Cut two yellow felt rectangles long enough to wrap around the shirt cuffs.
Add red stitching or ric-rac around the edges.
Sew or hand tack them onto the sleeves.
Step 3: Add Cow-Print Details
Use leftover cow-print fabric to make simple patches for the shoulders or upper legs.
If you do not have cow-print fabric, cut irregular black shapes from felt and place them on white fabric.
Step 4: Add Red Trim
Sew red ribbon around the collar, sleeve cuffs, or along the front of the shirt.
Even a small amount of red trim makes the costume instantly more recognizable.
Step 5: Finish the Cowgirl Look
Add a red bandana, western-style hat, boots, and a toy sheriff badge if you already have one.
For trick-or-treating, turn a small canvas tote into a western treat bag with a felt star.
