Looking for a Halloween costume that is cute, comfortable, inexpensive, and easy to make at home? This DIY strawberry costume checks every box. Instead of buying a costume that may only be worn once, you can transform an oversized red or pink sweatshirt into an adorable strawberry outfit using a few pieces of felt and basic sewing supplies.
This project is especially good for kids because the finished costume is soft, warm, and easy to move around in while trick-or-treating. It is also beginner-friendly, so you do not need advanced sewing skills or a complicated pattern.
Before buying a brand-new outfit, browse these girls’ Halloween costume ideas from everyday clothes for simple inspiration. In this step-by-step tutorial, you will learn how to make a DIY strawberry Halloween costume from an oversized sweatshirt, complete with felt strawberry seeds, leafy details, and an optional strawberry stem headband.
Why Make a Strawberry Sweatshirt Costume?
An oversized sweatshirt already has the perfect rounded shape for a strawberry costume. Adding a few simple embellishments instantly turns basic clothing into something playful and recognizable.
This costume is also easy to customize. Use bright red for a classic strawberry, soft pink for a sweeter pastel version, or even hot pink for a bold modern look. Pair the finished sweatshirt with leggings, tights, sneakers, or boots your child already owns.
Because most of the decorations can be made from inexpensive felt scraps, this is also a great budget-friendly Halloween upcycle project.
Materials You Will Need
To make one DIY strawberry sweatshirt costume, gather:
- 1 oversized red, coral, or pink sweatshirt
- Green felt or fleece
- White, cream, pale yellow, or light pink felt for strawberry seeds
- Coordinating polyester thread
- Sewing machine
- Hand-sewing needle
- Fabric scissors
- Paper scissors
- Pins or sewing clips
- Fabric marker or tailor’s chalk
- Measuring tape or ruler
- Paper for templates
- Iron and ironing board
- Optional fusible web
- Optional fabric glue
- Optional green headband
- Optional polyester fiberfill
- Optional green ribbon or elastic
Felt and fleece are ideal for this costume because their raw edges generally do not fray, making the project much quicker.
Upcycled Strawberry Costume From Oversized Sweatshirt
Step 1: Choose and Prepare the Sweatshirt
Choose an oversized sweatshirt that reaches at least to the upper thigh if you want the costume to resemble a strawberry dress.
For younger children, sizing up one or two sizes often creates a cute rounded silhouette without making the garment difficult to wear.
Wash and dry the sweatshirt before beginning.
Lay it flat on your work surface and lightly press out any wrinkles. Avoid stretching the ribbed neckline, cuffs, or hem while pressing.
Step 2: Plan the Strawberry Design
Place the sweatshirt front side up.
Before cutting anything, decide how many strawberry seeds you want to add. Approximately 15 to 25 seeds usually works well depending on the sweatshirt size.
Scatter them unevenly rather than arranging them in perfectly straight rows. Real strawberries have naturally irregular seed placement, and this makes the costume look more playful.
Leave some open space around the neckline for the green leafy collar.
Step 3: Make a Strawberry Seed Template
Draw a simple teardrop or oval seed shape on paper.
For a child’s sweatshirt, try making each seed approximately:
- 1 to 1 1/2 inches long
- 1/2 to 3/4 inch wide
Cut out the paper template.
Test it against the sweatshirt. If it looks too large or small, resize it before cutting your felt.
You can make two or three slightly different seed sizes for a more handmade look.
Step 4: Cut the Strawberry Seeds
Trace the seed template onto white, cream, pale yellow, or soft pink felt.
Cut approximately 15 to 25 pieces.
You can also mix two similar shades for extra dimension.
Arrange the felt seeds across the front of the sweatshirt first. Once you like the placement, add a few to the sleeves and back.
Step 5: Attach the Strawberry Seeds
Pin or clip each felt seed in position.
For the cleanest and most durable finish, stitch close to the edge of every seed using a straight stitch.
You can also use a narrow zigzag stitch.
If you want an even faster costume, apply fusible web to the back of each felt piece before positioning them. Press according to the manufacturer’s instructions, then add a few stitches for extra security.
For a completely no-sew version, fabric glue can also work, although sewing will hold up better through repeated wear.
Step 6: Make the Green Leafy Collar
Now create the strawberry’s leafy top.
Measure around the neckline of the sweatshirt.
Draw several simple pointed leaf shapes onto green felt. Each leaf can be approximately 3 to 5 inches long depending on the costume size.
Cut five to eight leaves.
Arrange them around the neckline with the pointed ends facing downward over the chest and shoulders.
Slightly overlap the leaves to create a fuller strawberry-top appearance.
Step 7: Attach the Leaves
Pin the leaves around the neckline.
Be careful not to sew directly through the stretchy ribbed neck opening in a way that prevents it from stretching over the child’s head.
A good option is to attach each leaf just below the ribbing.
Stitch across the top edge of each leaf using a straight or zigzag stitch.
For a dimensional effect, leave the pointed ends loose so they lift slightly away from the sweatshirt.
Step 8: Add Leaves Around the Hem
For an extra-cute strawberry shape, add several green leaves around the bottom of the sweatshirt.
Cut medium-sized pointed leaves and position them around the lower hem.
Attach only the upper edge of each leaf, allowing the tips to remain loose.
This detail works especially well if the oversized sweatshirt is being worn like a tunic dress.
Step 9: Make a Strawberry Stem Headband
A matching strawberry stem headband completes the costume.
Cover a plain headband with green ribbon or fabric if desired.
Cut three to five green felt leaves and arrange them across the top.
For a small stem, roll a rectangle of green felt into a tube and hand stitch it closed. Lightly stuff it with fiberfill if you want it to stand upright.
Sew or glue the stem between the felt leaves.
You now have an easy strawberry crown that instantly makes the costume more recognizable.
Step 10: Style the Costume
Pair the sweatshirt with:
- Green leggings
- Red leggings
- White tights
- Pink tights
- Sneakers
- Rain boots
- Mary Jane shoes
For colder Halloween weather, layer a long-sleeve shirt underneath and add warm leggings without changing the look of the costume.
Step 11: Check the Fit
Have your child try on the finished strawberry sweatshirt.
Make sure the neckline still stretches comfortably and that none of the felt pieces restrict movement.
Check that all appliqués are securely attached.
Trim loose threads and reinforce any pieces that feel loose.
Step 12: Final Press and Finish
Turn the sweatshirt inside out and lightly press from the wrong side.
Avoid pressing directly onto synthetic felt unless you know it is heat-safe.
Reshape the leaves with your fingers and give the costume one final inspection.
Your DIY cute strawberry costume from an oversized sweatshirt is finished!
