Choosing the Best T-Shirts
Not all t-shirts work equally well for this project.
Best Types of Shirts
Look for:
soft cotton jersey
lightweight knit fabric
oversized relaxed-fit shirts
matching or coordinating colors
minimal side shaping
Avoid:
very fitted women’s tees
thick heavy fabric
stiff structured shirts
Men’s t-shirts usually work best because they have straighter cuts and more fabric to work with.
Thrift stores are a fantastic place to find inexpensive shirts for upcycling projects like this.
How to Make a DIY T-Shirt Sundress
Step 1: Cut the Top Shirt
Start with the shirt that will become the bodice of the dress.
Cut across the shirt approximately 7 inches below the armholes.
This creates the fitted upper section of the sundress while keeping the original neckline and sleeves intact.
If you want a more cropped waistline, you can cut slightly higher.

Step 2: Cut the Bottom Shirt
Next, take the second t-shirt and cut directly underneath the armholes.
The bottom portion of this shirt becomes the skirt of the dress.
One of the easiest parts of this project is that you can keep the original t-shirt hem intact, which means less sewing and a cleaner finished look.
Step 3: Sew the Pieces Together
Turn both pieces inside out.
Match the raw edges together at the waist and pin around the opening.
Sew the bodice and skirt together using a stretch stitch or narrow zigzag stitch.
Because knit fabric naturally stretches, you don’t need complicated seam finishes for this project.
Step 4: Add Elastic to the Waist
To create shape and give the dress a flattering fit, sew elastic along the inside waistband seam.
Measure elastic comfortably around your waist before attaching it.
Stretch the elastic slightly while sewing to create gentle gathers.
This step transforms the oversized t-shirts into a comfortable fitted sundress silhouette.
Step 5: Customize the Neckline (optional)
I adjusted the neckline because it felt too tight. The neckline was widened and finished with an added trim piece.
You can also customize your neckline by:
creating a scoop neck
making a wider boat neck
adding straps
trimming the sleeves
turning it into a tank dress
This is one of the best things about DIY clothing projects — you can personalize the design to suit your own style.
Easy Ways to Customize Your Sundress
Once you make one version, it’s easy to create different styles.
Fun Customization Ideas
Add pockets
Use contrasting shirt colors
Create a color-blocked design
Add lace trim
Use graphic tees
Turn it into a maxi dress
Add a drawstring waist
Create a beach cover-up version
You can even coordinate it with handmade accessories like a tote bag or sun hat.

Tips for Sewing with Knit Fabric

Helpful Beginner Tips
Use ballpoint sewing needles
Don’t pull fabric while sewing
Use clips instead of pins if fabric curls
Test stitches on scraps first
Press seams gently
Knit fabric naturally stretches, which makes fitting more forgiving than traditional woven garments.
